in a tribe in Africa (i watched it off a clip on TV. this technique does exist, but i forgot what it is called, only that i know on how to resist and bare pain.) every year, every male in the tribe has to do a test that will see how much they are able to bare physical pain. the tribe goes to the jungle to find bullet ants. when they find them, they collect them then put then in a container for the test. when they get back, they put the ants too sleep then they stick them onto mitts, with their sting side of them pointing inside the mitts. their sting of a bullet ant is as painful as 50 bee stings. so if you can imagine each hand in each mitts full of bullet ants, stinging your hands at the same time and you have to hold it there for 15min and if you take them off, it is a disgrace to their people and the process starts when they are 10 years old. when it's over, it means that you are a man and if anything painful happens to you, they are able to push through it because they already know how to bear it because they have felt worse.
