Tofauti ndio hiyo kaka.
In @Aviator s case, I think he/she was born trying to hi-five people with his/her feet, hence the spread. Jiggers labda akuwe nazo kwa akili, kama brother yake @Introvert
One thing that would interest me as a child was the difference in feet between watu wa ushago na born tao. People who'd spent more time walking barefoot have more spread out toes and better balance. Tao people with their "cute" feet can't go anywhere barefoot and suffer more knee and ankle...
