There is a day in everyone's childhood when they first learn what "natural selection" is, and then there is another day a few years after that when they see it in action, as all of the pretty girls gather around the virile star quarterback and spit on the chubby kids when they walk by. It's easy to spend the rest of your life thinking that your bad luck with the ladies is just evolution trying to filter your weird face and frail physique out of the gene pool.
But that's not entirely true; a lot of what keeps the bouncers from letting you into the best clubs also gives you some important advantages. For instance ...
#5. Tall People Make Good Models, but Short People Live Longer
Let's face it: People don't usually consider "short" to be a synonym for "sexy" -- there's a reason Tom Cruise has made a career of hiding the fact that he's only 5'7". But there is one benefit of being short, and it's not that you can be smuggled in a suitcase: Taller people are destined to die sooner than their stumpy-legged peers.
Manute Bol: Dead. Muggsy Bogues: Alive. But still can't ride a roller coaster.
In fact, researchers have found a multitude of studies showing that shorter people generally live longer than taller people, and this isn't just some random coincidence that scientists are confusing with a real pattern -- they base these findings on studies that have been done all over the world. For example, the longest-living people are from Okinawa, Japan, and the average height of their elderly is a mere 4'9". They've also found that taller people contract heart disease and cancer more easily, while in shorter cultures, such as some African tribes, these diseases are virtually nonexistent.
"Hold on, smart guy," you may be thinking, "If this is true, then why do scientists say that we're getting taller on average, as well as living longer?" Well, it probably has a lot to do with the fact that our knowledge of medicine is much better than it used to be. While taller people are generally more sickly, we have the medical expertise to kind of keep up with it.
"Damn, our deductible's going to go up again, isn't it?"
How are we so sure? Because coronary heart disease was rarer than a healthy meal at Taco Bell back before the 20th century, during a time when people were on average 4 inches shorter than today. And in countries whose populations have only recently increased in height, such as Singapore and India? Yep -- CHD is more prevalent.
And this isn't just Mother Nature being racist -- there have also been studies that very obviously point out the connection between height and longevity, all within the same peoples, and even the same profession. Look at the charts yourself:
The first chart shows baseball players of the 20th century, while the second chart shows the average Frenchman in the 19th century. The pattern? Shorties live longer lives.
So what are the biological reasons as to why this occurs? Other than the fact that it's probably much easier to get your head caught in ceiling fans, scientists speculate that, since taller people have more cells in their bodies, they are more exposed to carcinogens, and so are more at risk of developing cancer. And how much is this risk, exactly? Researchers have found that for women, every extra 4 inches of height you have over 5 feet is another 16 percent chance of developing cancer. That's right -- you're more likely to get sick simply because there is more of you. It sounds like cartoon logic, but it also appears to be true.

#4. Ugly Men Are More Fertile
So you rolled a less than average score in the genetic lottery. You've probably had to spend your whole life watching jealously while better-looking dudes blazed through entire cheerleading squads. Well, there may be some small consolation in the fact that Johnny Adonis over there might be shooting blanks. Studies have shown that there's a connection between how attractive you are and your sperm count, and it's not the one you think: Unattractive males are just more fertile.
You might think that this makes the opposite of evolutionary sense, but evolution knows what it's doing, which is why you're not in charge of it.
Think about it: Nature already assumes that attractive guys are getting more action, but that doesn't mean they're able to produce sperm faster than anyone else, so biology forces them to conserve their ammunition. If you're unattractive, on the other hand, your junk knows that each time it comes into contact with lady parts might be the last, so it gives it everything it's got.
In the interest of full disclosure, the above studies were conducted on animals, not people. But that doesn't mean that nobody has gone ahead to see if it applies to human beings as well. When scientists tried to find the closest thing they could to an objective measure of male attractiveness, they found that guys with deeper voices tend to be more attractive to women. We assume that the first thing they did with this information was try to invent some kind of voice-deepening drug for their own use, but the second thing they did was test their sperm count ... and yes, the Justin Biebers were packing more heat than the James Earl Joneses.

#3. Big Noses Are Healthier
People are so self-conscious about the size of their noses that, in the U.S. alone, there are 50,000 rhinoplasties done per year. When people look in the mirror every morning, it's clear that they don't want to see a whole bunch of nose staring back at them. But it seems now that cutting off your schnoz might have a negative effect on your health. And we don't just mean if you're doing it yourself.
Researchers have found that big noses give you better protection against bacteria and infections. And although you might assume that an unusually large nose would be more adept at Hoovering up large swaths of the environment, it turns out that the bigger the nose, the better it is at keeping the world out.
"Hey, I'm Lungs' friend, Oxygen, m- my name should be on the list ..."
To test this, researchers made two artificial noses, one of them 2.3 times the size of the other. They found that the bigger nose inhaled 6.5 percent fewer particles.
Wait. How would the bigger nose inhale less of anything? Well, a bigger nose doesn't mean you breathe more. You still need the same amount of air. It's just that if you have a bigger nose, it's more likely to suck in air instead of your mouth. And that's good, because your nose is designed as a filtration device, but your mouth isn't. So the further all those diseases, pollens and anthrax spores have to travel, the greater the chance that they're going to get tangled up in that jungle of nasal hair in your enormous honker.
And you don't even have to worry about breathing three months of crap because you're too lazy to change the filter.
And this even works if you're a mouth-breather. The experiment showed positive results even when the researchers had the fake-nose monstrosities suck in the air around their lips. Apparently, this is because a big nose simply gets in the way of airborne particles before they can invade your respiratory tract. If we had any sense at all, we'd be attracted to huge beak-nosed people, knowing they'll make our children more resistant to disease. But who cares about that? They look weird.
