when i was in second grade, i used to believe that adults had a slower pulse than kids. so i took my pulse, decided that it was really slow, and reasoned that i was secretly an adult in a child's body. then i would take the pulse of other kids at school, and if theirs was as slow as mine, i would tell them how they were secretly adults, just like me. most kids i told this to were fascinated. we had a little club going for a while.
