Consider these claims....
 An elephant can pull twice its own weight.
 A bumblebee can pull 300 times its own weight.
 A flea can pull 160,000 times its own weight.
Question 1: Assuming your powers were equivalent to that of an elephant, a bumblebee, or a flea, how much weight could you pull?
Question 2: How many fleas would be needed to pull your weight?
Note: As to why this equivalency does not hold, consider the web site Ant And Flea Super Feats .
