I'm an especially hairy person. It takes me ages to get dry after a
swim - much longer than most people. They're fully dressed and waiting
to go but I don't want to put my shirt because I'm still damp. If I
spent my life going in and out of the water, searching for shellfish,
this aspect of my anatomy would be significant handicap. I'd be much
more likely to suffer exhaustion or catch a chill.
