i used to have jumping contests with my friends. i usually won. but here's the most memorable one: while removing roof snow from a 3 story house i challenged my brother to a jump. i was on the roof at the corner. the snow was about 6' deep on the ground. i sat there for about 5 minutes thinking if i should jump. i jumped & won the contest!!! it took me 5 minutes to dig myself out of the snow!!!
