Useless knowledge?

Well... Q: do you know why your name is Mudd if you do something wrong? A: A doctor by the name Dr. Mudd saved Abrahm Lincolns assasin, the public thought that the assasin should die and the doctor saved him. Q: where did the saying "get on the ball" come from? A: when flying an airplane your leveling controller has a ball that goes to the side that is higher. You step on the rudder pedal that is higher thus- "getting on the ball"

Any knowledge all cannot be useless, so long as is oneself likes, manystudy general meetings have the advantage

A camel can lose up to 30% of its body weight in perspiration and continue to cross the desert. A human would die of heat shock after sweating away only 12% of body weight. The number of centenarians (100 years and older) has more than doubled since 1980 to about 50,000. Four in five were women. (And I really didn't need to know about the 10 spiders!) Good discussion here.

I found a few: 27% of female lottery winners hid their winning ticket in their bras. 3% of pet owners give Valentine's gifts to their pets 31% of employees skip lunch entirely. 45% of Americans don't know that the sun is a star.

More people die from getting hit on the head by a coconut then eaten by sharks.

this is the useless knowledge
