Climbing to high altitudes makes it harder and harder to breathe. There are even heights that, should you not have the proper gear, your body will not make it. It’s generally at twenty-six thousand feet or about five miles. Certain groups, however, are able to survive at high altitudes much better.
Indigenous groups like Tibetans have had generations of adaptation to increase their red blood cell levels and other things, which allows them to survive and even flourish at high altitudes. Going from sea level to higher places, like Colorado, for instance, is considered a change, but here we are referring to extremer heights.
Stretch Out Those Eyeballs
If you're looking for a wild party trick, check to see if you have something called globe luxation. It's an extremely rare condition that allows your eyes to actually protrude a little from their sockets.
With practice and some experimentation, you should be able to pop your eyes out of their sockets a little bit. Great for grossing out nephews. This condition comes with downsides such as optic neuropathy, thyroid eye disease, and things like shallow orbit and floppy eyelid syndrome. They don't sound like they're any fun.
Sing Like the Best of Them
Learning you have perfect pitch doesn't just mean you're a good singer – it means you can mimic musical notes perfectly. Think about hearing a D minor and naming it on the spot without hesitation. Plenty of people are said to have it, but only about one in ten thousand really possess the trait.
For the others, it's probably a combination of training and luck. Scientists are still in discussion as to whether this is a learned trait or something that is present from birth. Some have thought that with enough training, a true perfect pitch can be developed, but it takes a lifetime of work at the very least.
The Fish People of Southeast Asia
Unless we've been trying to increase our skills, most of us start panicking after about thirty seconds underwater. Not so for the people of the Bajau, a group of sea nomads from Southeast Asia. A study found that the Bajau, who commonly take dips in the ocean to fish, have evolved extra-large spleens that hold oxygen-rich blood cells in reserve.
Because of this, they're able to spend from five to ten minutes underwater without worry. A big spleen is going to help, but training yourself to spend longer and longer periods beneath the waves is going to help, too.
Never Get Lost
Some of us need directions to go to our mom's house, but there are some who seem to have a natural ability to keep going in the right direction. History has shown us skilled explorers that have, whether genetically or through learned traits, guided people without going astray.
Researchers at the Queensland Brain Institute discovered that this useful ability is mainly attained training in the environment you're in, and comes about slowly as your mind becomes more and more attuned to the small elements around you. Moving to a new area will, for the most part, reduce this ability.
