I was sitting, doing nothing this other day, and pressed my finger on a metal thing... when i out of the blue saw my finger print on this metal thing, i suddenly wondered: How much fat do a human got outside the skin... i mean... how much must one press once finger print to go emtpy of fat? Offcourse without any other input like food or water. Can i empty the body of fat just my pressing my finger against an empty spot like on a glass window or metal thing? Anyone know?
