Celebrity sighting

For those who care about such things, I saw Timothy Olyphant, notable for his services in the recent "Hitman", "Die Hard with a Vengeance", "Deadwood", and "The Girl Next Door", at the gym yesterday. He looked much, much older and grayer than he does on film. Also, he's not as tall as you might expect. IMDB tells me he's nearly 40. Never would have guessed that one.
