Re: Hands: Dominant, switching doesn't feel right, not sure on the holding hands thing and am at work so I can't verify. Pretty sure it depends on who is leading who, as the person on the "front" (leader) should having their wrist further forward. I suspect I'm dominant outside when holding hands and doing nothing / idly walking.
