Micajah,
Some idiot didn't get the science facts right, there is a DOMINANCE of one nostril, and it shifts every couple of hours to another one, but it sure is not 100% one nostril, in normal circumstances.

#5 Doesn't explain why raised hair follicles would help with warmth. It's because the erect hair (once upon a time fur) would trap air which is an effective insulator for the same reason fiberglass wool is used as insulation in the walls in some forms of construction (eg, Canada & USA).

Your stomach is constantly digesting itself

 

The stomach contains so many enzymes and acids that it slowly digests itself. Luckily the body produces cells quickly enough to replace the cells that get destroyed every day. We end up with a new stomach lining about every three days.
