Even at thirty, I've still got a bit of a complexion problem that I have to handle with kid gloves. If I go more than twelve hours without showering, it's back to the drawing board. It has become less of a problem the last two years or so. Whether that's due to better maintenance on my part or it slowly clearing up, I don't know.
When I take care of myself, though, I've got no real problems. Sometimes I think if I had a twin I'd never leave the house.
If pressed, I suppose I could be three or four inches shorter.
