As a baby I was born with a pituitary issue which meant my hands and feet were abnormally small. They never grew that large at all. I can run and walk fine and they’re not deformed or anything, just tiny. I might have some weird world record for smallest hands and feet on a fully grown adult!
A friend of a friend was born without arms and he does the same thing. His is up there on my list of most fascinating handshakes. He doesn’t pay bus fare either.
