Homeless, I can bend the index finger on my left hand at the first joint as well, and it seems to give me some special skill (don't ask why) at playing barre chords. Do flat feet count as a mutation? It's so bad that my ankles roll over and almost touch the ground. That's why I wear only high top sneakers & basketball shoes, because I need the support, either that or I'd fall over.
