im watching this show on discovery channel called "Beyond Human" or somethin to that effect, anyways they take people that can do some crazy stuff and test em to see if they are any different or if its fake.
First one was some chick that could free dive(1 breath of air) down to 400ft using some weight to drop her down, but she has to swim up using her own power,thats somethin to see, crazy stuff, she could also hold her breath for 4:20.
Then they had this guy that could do math faster then anyone and anything, they gave him random equations and he dished it out faster then they could type it on the calculator, example, they gave him 87 x 87 x 87 = 600,000 somethin they gave him the 600,000 somethin part and asked him what number by 3 it was, before i even knew what was goin on he says 87! truely amazing!
The last guy bungee jumpd from a 200 somethin ft bridge with some friends, the cable snapped and they hit goin 80mph, the did a test to see if water is really harder or as hard as cement from 200 ft and they found that water is in fact not near as hard a cement,
neways all those people survived the fall and fully recoverd, they dropped 2 fake bodys( made out of stuff the same composition of a body and with bones) and dropped 1 on water and 1 on land, both would have died.
they found that at the angle the rope broke, it sent them at a 45 degree angle into the water, they were wearing life vests also, those 2 things are what saved them, had the rope broken 1 sec sooner they would have spaltted flat into the water and broke up into pieces, had it from much later they would got flung into rocks and died, amazing stuff, what a lucky guy.
The human body is truely amazing!
