On transit geeks and aging

My beloved Bus Nerd celebrated a birthday on Wednesday. He’s not old enough for a midlife crisis yet, but it did get us to thinking:

How, exactly, does a bus nerd of a certain age attempt to recapture his youth? Yes, he can chase after younger bus chicks or get hair plugs, but what’s a middle-aged bus nerd’s equivalent of a red sports car?

Any thoughts? I’d like to be prepared.
