15 Airports That Make Travel a Nightmare


                                World's Worst Airports

Oh, the indignities of air travel: crammed in small containers, can’t move, subjected to foul smells, elbow-to-elbow humanity, accumulations of trash, unplanned delays — and that’s just in the airports.

Worst weather: Chicago O’Hare International Airport

O’Hare (ORD) is not only pummeled by snowstorms whose winds howl out of Canada to pick up moisture off Lake Michigan. In summer, thunderstorms prowl the skies; spring and fall bring fog. Thirty snow days a year; 38 thunderstorm days; 36 inches of rain a year; chronic wind problems — that’s a lot of bad weather.

Worst weather: Frankfurt Airport, Germany

Second prize for worst weather goes to Frankfurt (FRA): It’s in a fog-plagued river valley, gets a fair amount of snow and is subject to frequent rainstorm delays as well.
Dishonorable mention: The fog at San Francisco International Airport (SFO) is chronic, though not acute; rarely is the airport shut down. In January 2010, it experienced fog 28 out of 31 days.

Worst delays: London Heathrow International Airport

Heathrow (LHR) wins this prize. The world’s No. 1 international airport is the most delayed major hub in Europe; delays average close to 20 minutes. With just two runways that are close together, it’s no surprise that holdups are caused as much by air traffic as by weather. At least the English countryside is green and scenic while you are circling above it. But when bad weather brings complete shutdowns (as it did in late 2010), some stranded passengers had to wait outside in tents.

Worst delays: Newark Liberty International Airport, N.J.

Second prize: Newark Liberty (EWR) is another international hub with essentially one runway. At the world’s No. 29 airport, planes can sit on the tarmac for hours waiting for a takeoff slot. Passengers either cook in the fuselage or in the crowded terminals.
  Dishonorable mention: Amsterdam Airport Schiphol (AMS) averages 15 minutes in flight delays. John F. Kennedy International Airport in New York joins Newark among the worst-delayed airports; the two major hubs divide air space for hundreds of planes with New York’s La Guardia Airport.

Hardest to navigate: Phoenix Sky Harbor International Airport

Phoenix (PHX), No. 19 in the world, consists of three terminals, five concourses, 10 wings and a confusing maze of bus routes to serve them. Bonus health prize: Temperatures can reach 187 degrees Fahrenheit on the asphalt airport drives. Inside, airport officials chill the terminals so passengers won’t decay.

Hardest to navigate: Madrid-Barajas Airport

Second place: Madrid (MAD) is cited by frequent travelers as a maze of shops and walkways in which the only signs are for the duty-free stores. Interterminal connections are fraught with challenges, and passengers are required to cart their belongings in bins to security radar by themselves — quite a challenge for some senior travelers.
Dishonorable mention: Heathrow has five terminals and buses that wander circuitously among them like army ants. One must allow at least two hours for connections between terminals.

Hardest to get to: Washington Dulles International Airport

Dulles (IAD) is the major hub for the U.S. capital, but it is so far away from Washington, D.C. — 26 miles — that if it were in some parts of Europe, it would be in a different country than the city it supposedly serves. No, there isn’t a subway, train or any other efficient conveyance between the city and its airport (one is planned, though the first phase won't be complete until 2014). You can take a taxi if you get the OK from your bank lending officer beforehand.

Hardest to get to: Beijing Capital International Airport

Second prize: Beijing International (PEK), No. 3 in the world, isn’t as far from its capital as Dulles. But Beijing traffic is still tied up from the Olympics three years ago; even the city’s most experienced limo drivers cannot find ways around the tie-ups.
Dishonorable mention: Denver International Airport is far, far out on the plains northeast of its city. No light rail here, either. At least the High Plains winds sweep away whatever toxic residue remains from its former neighbor, the Rocky Mountain Arsenal. (No, that’s not the same as the soccer team.)

Dirtiest: Sheremetyevo International Airport, Moscow

Moscow’s airport (SVO) is old, Soviet-made, falling apart, rarely cleaned, and stinks to high heaven of cigarette smoke. In the new terminal, it stinks of smoke and paint. Bonus democracy prize: Soldiers guard some seats for Russian oligarchs.

Dirtiest: Jakarta International Airport, Indonesia

Second prize: Jakarta (JKT) has all the same problems as Moscow’s airport — and it’s in the tropics, so everything festers.
Dishonorable mentions: Charles de Gaulle (CDG) Airport in Paris, where the lack of cleaning is often cited by frequent travelers, and Miami International Airport (MIA), another subtropical bug zoo.

Most crowded: Hartsfield-Jackson Atlanta International Airport

Hartsfield (ATL) is the world’s busiest airport, shuffling close to 90 million passengers a year. Restroom lines can surpass 15 minutes; food-court lines go out the door and into the next concourse. The numerous designated smoking areas in the terminals fail to contain the smoke.
  Second prize: Frankfurt (FRA) has gate waiting rooms that are invariably designed for the 120 passengers on a 737, but must hold the 350 passengers on an intercontinental 747. Got deodorant?

Ugliest: Haneda Airport, Tokyo

What are those spiral objects guarding the Haneda (HND), the world’s fifth-busiest airport, like gateposts? Concrete Slinkies? Really, really big DNA models? Discarded Brobdingnagian elastic bandages? No, they’re parking structures. We think.

Ugliest airport: McCarran International Airport, Las Vegas

Second prize goes to Las Vegas (LAS). The outside of the world’s No. 17 airport is unremarkable. But indoors, travelers walk past rows of slot machines and poker machines, blinking and winking and beeping and squawking. Scores of lounge lizards thin as sticks feed their life savings into the machines. That’s ugly, folks.
  Dishonorable mention: Dulles’ famous Eero Saarinen 1962 design today looks like the roof blew off a mobile home. Bonus aesthetic appeal is provided by the truly bizarre twin-capped buses (“mobile lounges”) that shuttle passengers around the tarmac.

Worst overall runner-up: John F. Kennedy International Airport

JFK airport is crowded, dirty, fraught with delays and staffed by customer-service personnel who have degrees in disdain. Its once-hip design looks dated and awkward, like a really large athletic bra. Cigarette smoke fills the air inside in a few bars and restaurants.
Dishonorable mentions: Los Angeles International Airport (LAX) is tawdry, coming apart at the seams, crowded and poorly planned. Heathrow is all of the above, and has frightful delays. Jakarta is dirty, crowded, ugly and unpleasant. Same for Madrid, which was derided by several of our correspondents.

Worst overall: Paris-Charles de Gaulle Airport

This Paris hub is the unanimous choice, derided universally not only for its frequent delays — 15 minutes, on average — but also for a difficult-to-navigate layout, unfriendly customer service, dirt and general unsavoriness. Here, at the world's #6 airport, passengers complain not just about lines, rude staff, dirt, bad food and the confusing layout, but about the bands of homeless transients who apparently live there.

A Visual Guide to Deflation

 Deflation is inflation’s polar opposite. It’s what happens when prices go down and you get more bang for your buck. Sounds good right? But deflation, like inflation is complicated and much less understood than inflation. It can lead to what’s called the deflationary spiral and grind the whole economy to a halt. In this second of a two-part series we take a look at deflation.

The Most Revealing Psych Experiments

Psychology is the study of the human mind and mental processes in relation to human behaviors - human nature. Due to its subject matter, psychology is not considered a 'hard' science, even though psychologists do experiment and publish their findings in respected journals. Some of the experiments psychologists have conducted over the years reveal things about the way we humans think and behave that we might not want to embrace, but which can at least help keep us humble. That's something.
1. 'Lord of the Flies': Social Identity Theory
The Robbers Cave Experiment is a classic social psychology experiment conducted with two groups of 11-year old boys at a state park in Oklahoma, and demonstrates just how easily an exclusive group identity is adopted and how quickly the group can degenerate into prejudice and antagonism toward outsiders.Researcher Muzafer Sherif actually conducted a series of 3 experiments. In the first, the groups banded together to gang up on a common enemy. In the second, the groups banded together to gang up on the researchers! By the third and final experiment, the researchers managed to turn the groups on each other. 
2. The Stanford Prison Experiment: Power Corrupts
This infamous experiment to plumb the depths of evil in human hearts ended up affecting its lead researcher as much as its subjects. Psychologist Philip Zimbardo divided his participants into two groups labeled "prisoners" and "guards." It was conducted in a mock-up prison in a Stanford University basement. The prisoners were subjected to arrest, strip search, de-lousing, head shaving and other abuses. The guards were given clubs.The prisoners rebelled on the second day, and the reaction of the guards was swift and brutal. Before long, the prisoners were behaving meekly and with blind obedience, while the guards fully embraced their roles by taunting and abusing their charges. This one might be scientific confirmation of the idea that humans harbor evil tendencies. The planned 14-day experiment was halted after only 6 days due to increasing levels of abuse.



 3. Obedience to Authority: Human Capacity for Cruelty
In 1963 psychologist Stanley Milgram set out to test people's propensity to obey authority when ordered to hurt another person. The world was still wondering what happened in Germany during WW-2 that caused so much horror. Milgram's subjects were told they were to be the 'teachers' of a 'learner' (who was secretly in on the experiment). They were to deliver electric shocks to the 'learner' if he or she got an answer wrong. Worse, they were told to increase the shock if the 'learner' continued to get the answers wrong.Despite the screams and moans of pain from the unseen 'learner', the subjects continued to deliver ever more severe shocks if ordered to do so by the experimenter in the lab coat. They continued even when told they had rendered the 'learner' unconscious! The conclusion? Looks like we humans are quite easily able to set aside moral and ethical considerations when ordered by authority to violate them.
 4. Conformity: Not Believing Your Lying Eyes
From social identity theory psychologists got a handle on group dynamics and prejudices, how natural it is for groups to elicit conformity among their members. In 1951 Solomon Asch set out to identify just how much individual judgment is affected by the group.In a test environment in which undergrads were asked to render a judgment after other subjects gave deliberately wrong answers, 50% of people gave the same wrong answer when their turn came. Only 25% of test subjects refused to be swayed by the false judgment of the others, while 5% always went with the crowd. The finding was that a third of people will ignore what they know to be true and go with a falsehood if they're in a group that insists on the falsehood being true. What else will people do under influence of the group?
5. Lying to Ourselves: Cognitive Dissonance
One might begin to suspect that people must be pretty good at either ignoring their own feelings, beliefs and desires, or flat out lying to themselves (and getting away with it). In a classic 1959 experiment psychologists designed an experiment with level upon level of deceit to see just how much a person will ignore their own experience, even to the point of helping to convince someone else of something they know is not true.The human capacity for sustaining cognitive dissonance has since been confirmed in many other well-designed experiments. This capacity is linked closely with our desire to join and fit in with a group, adjusting our own values and beliefs about things to align with those of others. Perhaps, knowing about these propensities, we can learn to avoid believing our own lies too much.
6. Memory Manipulation: Do You Really Know What You Saw?
In 1974 researchers designed an experiment to test the reliability of memory, and whether it could be manipulated after the fact. 45 people watched a film of a car accident. Nine of those people were then asked to estimate how fast the cars were going when they "hit." Four other groups were asked an almost identical question, but the word "hit" was replaced with the words "smashed," "collided," "bumped" and "contacted."Those whose questions included the word "smashed" estimated the cars were going 10 mph faster than those whose word was "contacted." A week later participants were asked about broken glass (indicative of more serious accident), and those whose trigger words were more forceful said they remembered broken glass even though the film had depicted none. Looks like something so subtle as a single descriptive word can manipulate memories of an event!
7. Magic Memory Number: 7

Psychologist George Miller wrote in 1956 that he was "persecuted" by the number 7, which kept intruding on his mind while contemplating data or reading journals. Sometimes it was slightly higher, sometimes slightly lower, but always it hovered around 7. Miller theorized that this 'magic' number represents the number of items we are able to hold in our short term memory at any given time. Plus or minus 2.More recent studies have demonstrated that people are able to 'group' items in short term memory - thereby being able to hold more individual items - yet even there the total if groupings are considered units, the number comes out to 7. Plus or minus 2. Maybe this is why human cultural belief systems historically considered the number 7 to be especially important to the gods!
8. Anatomy of Mass Panic: War of the Worlds
Orson Wells broadcast an adaptation of H.G. Wells' War of the Worlds on radio in 1938, causing panic in nearly 3 million of the 6 million people who listened to the broadcast. Princeton psychologists later interviewed 135 New Jersey residents about their reactions to the broadcast.A surprising number of frightened people never bothered to check out the validity of the broadcast, and some highly educated individuals believed it was true just because it was on the radio and thus "authoritative." We like to think we're more sophisticated today and wouldn't fall for such an obvious dramatization, but don't be too sure, Media manipulation of our emotions and desires is a regular art form these days. Just ask Madison Avenue!
9. The Bargaining Table: Threats Don't Work
Luckily, the behavior of individuals is both less deceptive and less violent than the behavioral 'norms' of groups. In the area of diplomacy among individuals and groups, people attempt to get concessions they want or need from others. Usually without having to give up too much in exchange. Researchers Morgan Deutsch and Robert Krauss tested two factors involved in the crafting of agreements between humans in 1962: communication and threats.This complicated economic experiment found that cooperative relationships between the bargainers are more beneficial to both parties than threats, either unilateral or bilateral. Not exactly a rousing endorsement of capitalistic winner-take-all competition, but in view of the current economic situation perhaps the results of this experiment should be kept in mind as we craft a recovery!
10. Risky Behavior: Prospect Theory
Speaking of the economy, researchers Daniel Kahneman and Amos Tversky studied decision-making in risky situations and developed a theory about it that garnered a Nobel Prize and has been used to develop predictive economic models and influence marketing campaigns.Turns out that it's all about framing. People behaved differently depending on how the situation was presented. If considered in terms of losses, people were more likely to take risks. They were less likely to take a risk of the situation was presented in terms of what they stood to gain. This seems strangely opposite of what we'd tend to guess, so it's something to bear in mind next time you're trying to bluff at the poker table.

Boxing Kangaroos!

 A flurry of blows sees both creatures' heads knocked backwards as they struggle to maintain their balance. Faint lassos of spittle unfurl through the air, tribute to the ferocity of the fight; a torn ear testament to past battles. It beats photographer Julian Robinson how these battling beasts survive such encounters, but survive they do. Male kangaroos are known for their pugilistic prowess and they share a boxer's upright stance and combat skills. Bouncing nimbly on powerful hind legs, sizing each other up, the two opponents launch sudden combinations, jabbing and grappling with lightning forelegs to gain the advantage, then lashing out with raking kicks – haymakers far more devastating than any man's. Each razorsharp hind claw has the potential to disembowel the other animal. It's as well each kangaroo's organs are protected by tough skin and a thick layer of abdominal tissue. When these body blows land, the loud thumps are like the beating of a tribal drum.
 Although far from unfamiliar with Australia’s Eastern Grey Kangaroos, Julian Robinson was quite unprepared for the spectacle that was to unravel before his eyes. He stumbled upon the slugfest in 2006, “while I was with a car full of Greening Australia people, doing a photo series for World Environment Day,” he told Environmental Graffiti. “We'd come to a property [about 20km north-west of Canberra, ACT] to look at some tree plantings and take some photos.” What he captured on his camera was an incident far more impressive – and brutal – than even the most gnarly of saplings!
 As we drove up I saw the roos ahead on a rise and asked the others to stay in the car,” says Julian. “I jumped out of the car and ran up to them behind cover of some trees. Then I had to break cover to take the photos. One of the roos saw me, took a quick look at me and was considering scampering off when the other one caught him unawares and biffed him hard enough to almost knock him off his feet. The fight was back on and they ignored me totally for the rest of the time.”
The dangerous forepaw claws are clearly visible in the first two shots above. “They keep their heads out of range as far as they can, with good reason,” explains Julian, adding: “You don't see many roos standing up tall. These guys sure got as high as they could get.” Laws of nature. Needs must.
 Sometimes the kangaroos engage in these bouts with one another playfully or for practice, but often, as Julian explains, “it's all about male dominance, and a contest for 'owning' the group of females. Standard old bull vs young bull stuff.” Standard maybe, but there's nothing run of the mill about witnessing the phenomenon first hand. At peak mating season, competition can be fierce among the big males if there is not a high enough proportion of 'sheila' kangaroos coming into heat.
The so-called boxing is kangaroos' natural defensive behaviour. Still, observing the way that they hold attackers in place with their 'arms' and kick out with hind legs whose claws can slash and eviscerate is enough to make anyone wince. “Opinion seems to be divided as to how much damage they do, but it certainly appears full on and very dangerous, especially the kicking to the gut,” says Julian.
 If there were any doubt as to the damage these animals can do to one another, it's dispelled in the next shot, which shows one kangaroo appearing to kick at the scrotum of its enemy while standing on its tail. Julian explains:
“These are big roos, standing over 7 feet (2 m) when on their toes trying to gain the height advantage. They attempt to rip the ears, eyes and nose of the opposition with the big sharp claws... More dramatically, they stand high on their tails while holding on to the opposition for support, then plunge their hind feet... into the belly of the victim, actually attempting – I think, watching as closely as I could – to do permanent damage to the reproductive organs.”
 The final shot seems to show an end to the struggle – Julian thought so – “but it turned out to be just a pause,” and after one more photo he ran out of storage on his camera. “By the time I went back to the car to get a new card and encouraged my comrades to come and have a look, the roos took one look at us and hopped away, one behind the other. Whether there was an acknowledged winner and loser I will never know.”
Too late to capture the finale, but in the right place at the right time to catch the battle's beginnings and see most of the epic 10-minute encounter between a dominant male and a challenger with his own eyes. “I don't know which was which [dominant male or challenger], but in the end one looked a bit more foolish than the other and casually sidled off a bit worse for wear, as in limping a bit,” he concludes.
An ex-project manager/systems engineer in air traffic control systems and radar, Julian Robinson switched careers after developing Multiple Chemical Sensitivities which rendered him unable to inhabit hotels and office environments. However, he still keeps his eyes to the skies as a photographer of birds as well as other wildlife and panoramic landscapes – an occupation he embarked on after photographing a rare parrot that had 'invaded' the northern suburbs of Canberra in 2006.

The Amazing Sex Life of Orchids

 Ophrys apifera
We all know or have read about the wild girls, the ones who use trickery and deceit to lure a man into their bed, or those who like a little kink with their sex to spice it up. Well, there is a group of flowers whose sex life is as naughty as it gets, and we humans could take lessons from them. 
 Orchids have evolved myriad ways of attracting their partners in reproduction, even to the point of entrapping and kidnapping them. They use every trick in the book, from sexy dresses to perfumes and bondage. And for a few that are unable to attract a partner, no asexual reproduction for them... they have learned how to have sex with themselves. When it comes to orchids and sex, drama abounds! Follow me into their pornographic world.
 Fly orchid
As its name suggests, the fly orchid is totally dependent on flies for pollination. To ensure that flies are lured to them, orchids use two different forms of trickery. First of all is the obvious visual trickery - the flowers look like the abdomen of a female fly but they also mimic the scent of the female. They go farther though - they don't mimic it exactly, just a little off so they are exotic smelling while still familiar. Rather like the red-headed beauty men swarm to at a party. Studies have that shown the male flies prefer the exotic fakes over their real partners until they realize they aren't mating, and that takes a few tries.
 One study found this preference was so strong that: "And indeed, male bees have the hots for exotic perfume. Given the choice between a dummy infused with the pheromone cocktail produced by the girl bee next door and another one with the bouquet of a female from another population, the males visited the scent that was new to them 50% more often. But orchid scent, with yet greater differences in the pheromone mix, was even more popular. In choice tests it attracted males up to five times as often as that of a local female. Manipulating the natural perfume blend of the bees to mimic that of the orchids also nearly doubled the bees' attractiveness to males."
 Hammer orchid
The Hammer orchids of Australia are even crueler. At least the poor fly orchid doesn't completely waste all his energy, but the dupe (Thynnid) wasp does. The female wasp is flightless and waits for the male at the top of a stem, where he carries her off to and they mate in mid air (rather romantic). As you can see, the hammer orchid mimics the female and does so very effectively. So much so that the wasps not only are lured to them but ejaculate on the orchid, getting nothing in return except using his energy and wasting his sperm.
According to another source: "The dupe wasp is so profoundly fooled that he even extends sexual pincers, called genital claspers, into the flower." It is a win-win situation for the orchid because the female wasp can reproduce asexually and produces males, while females are the result of actual mating. So by luring the dupe in to waste his sperm, more female wasps produce asexually, therefore there are more males to pollinate orchids.
 Bucket of bucket orchid
The dominatrices of the orchid world are the Bucket Orchids. They are pollinated by orchid bees that want the plant's aromatic oils to use them in their courtship dance with females. But what the poor bees go through to get them!
The orchids secrete the aromatic fluid into the bucket-shaped lip, and
the bee will often fall into the fluid at the bottom of the bucket. There are knobs inside that go one way but the rest of the bucket is lined with smooth hairs pointing downwards and so that they can't climb back up.
 Spout of bucket orchid
Finally following the knobs, the bees come to what looks like freedom, a spout exiting. The orchid, however, has no intention of letting the bee go yet. Instead, it constricts the spout and presses pollen packets against its thorax, keeping it there until the "glue" has set. Finally, it is set free to go and find another orchid and this time displace the pollen packets to pollinate it. It can take up to 45 minutes for the bee to escape the orchid as it is kept trapped for the orchids sexual needs and bent to her will.
 These aren't the only tricks in the orchid's sexual repertoire. In China, the Dendrobium Sinense species doesn't try to lure a bee, butterfly, bird or wasp by mimicking a female or its scent but instead mimics the distress scent given off by a honey bee. This lures hornets preying on honeybees to feed their larva as they think a bee is in trouble and will be easy pickings.
 Holcoglossum
A study in Nature journal found: "Here we describe a new type of self-pollination mechanism in the tree-living orchid Holcoglossum amesianum,in which the bisexual flower turns its anther against gravity through 360° in order to insert pollen into its own stigma cavity — without the aid of any pollinating agent or medium."
As we can see, the orchid's sex life is all about trickery and deceit. Humans have come up with lots of variations on the sex act and have rich fantasy lives but are staid and stodgy when it comes to reproduction compared to the twists and turns the orchid has managed to come up with!

Commonly Believed Myths about the Human Body

 We have learned much about our bodies through old wives' tales handed down from our moms and grandmothers and even in school, but not all of it is correct. Here we look at 10 misconceptions that might surprise you.
 10. Sleepwalkers should never be woken


Sleepwalkers are often confused and/or disoriented when awakened but this is far better than the danger of injuries that are common from tripping over things, walking into dangerous areas and more. Thus, wake them gently and help them get back to bed.
9. You will catch a cold if you go out in wet, freezing weather
There is no evidence to support this misconception at all. Viruses are more common in the low humidity time of winter and of course, people are gathered indoors more, so they spread easily but the only thing that going out in the cold does is perhaps lower your resistance to an infection you already have, starting some temporary sneezing and coughing.
8. Fingernails and hair continue to grow after death



 Neither continue to to grow. What does happen is that the cuticles and skin shrink after death, making it appear as if the nails and hair were lengthening.
7. Your hair grows back thicker and darker after shaving
 Another falsity: Uncut hair is tapered, so doesn't appear as thick as cut hair. Also, uncut hair has more exposure to the sun, which lightens it a little, making cut hair appear darker at first.
6. Conditioners and shampoos can cure split ends
 Not so, there are no cures for split ends beyond cutting them. Good conditioners and shampoos might help prevent them in the first place but anything purporting to heal them should be looked at with the same eye as you would look at snake oil.
5. Men think of sex every seven seconds
 It would make it hard to concentrate on needed things such as work if this were true, so good thing it isn't. Even though there is no way of measuring this properly, studies scientists have done show this is a huge exaggeration.
4. Different areas of the tongue taste different things
 The idea that taste buds in different areas of the tongue correspond to sweet, sour, savory and salty has been floating around for decades but is false. Every area of the tongue can taste every type; the idea that there was a tongue map came from a mistranslation by a Harvard professor, of a badly written and discredited German paper.
3. We use only 10% of our human brain
 William James, a psychologist in the 1800s, once metaphorically used the idea of 10% of the brain being all that was used at one time. This grew into the rumor that it was all the brain was overall and most of the rest was not understood or used as far as we know. Actually, the inactive neurons are just as important at any given moment as the ones actively firing at a point in time, and the 10% comes from varying areas at different times.
2. Sugar makes children hyperactive
 False! Twelve controlled, double blind trials have shown that there is absolutely no connection between children's behavior and their sugar intake. One thing was found, namely that parents rate their child's behavior as more hyper when they thought they had been given a sugary drink. "The studies included sugar from sweets, chocolate and natural sources. Even in studies of those who were considered “sensitive” to sugar, children did not behave differently after eating sugar-full or sugar-free diets," said Vreeman and Carrol who undertook the retrospective study.
1. Warts can be caught from other animals like toads
 Human warts are caused by a virus that affects only humans, the human pappiloma virus. They cannot be caught by animals with warts and certainly not by toads whose bumps are not warts but glands.
