Some people who claimed to know things about human physiology and biology once told me that when held in a hand, a permanent magnet affects blood cells (specifically ferrum in them) and makes your grip temporarily stronger (until the blood flow adjusts to the effect) at the cost of some harm done to muscle tissue due to unusual conditions. Is any of that true?
