65% of human body weight is oxygen! In January 2009, a fitness gym in London, England, set up weightlifting machines using people as weights! Believe it or not! The odds of a baseball fan being hit by a ball at a Major League game are 300,000 to 1!
65%?!?!? Then a 100-pound person would weigh 65 pounds of air! Then, the earth has about 790,854,451,200,000,000 million (That is a lot) SQ inches, so you get 1,162,556,043,264,000,000,000 pounds.
