As you get older, your brows can get, well, a little woolly. This change can happen slowly, making it harder to recognize (and leaving you scratching your head when people start offering you their seats on public transit). Resist the temptation to shape them yourself. Instead, ask your barber to do a trim during your regular visits. And while you're at it, have him take care of excess ear and nose hair too. Don't be shy—he's used to it.
