You know how you’ll occasionally look at your arm or you leg and see a cut or bruise and you have no idea where you got it?
This happened to me today when I put on a pair of shorts, except the bruise on my shin is roughly circular, and two inches across. How does this happen, exactly? You’d think I’d remember an impact against something big enough, and with enough force to cause such a large mark.
You’d be wrong, however. I have no idea when or how it happened.
