gifts, TOO MANY!
I just saw Gregory Benford as a talking head on NOVA, and really, is it fair that anyone should be a UC physics professor, and a fantastic SF writer (and now I read also, a CEO of biotech companies, in his retirement). And he was pretty good-looking too, in a big, blonde sort of way.
The winner so far in SF 12 is "Chu and the Nants" by Rudy Rucker; it says in the intro he's another one of these, a retired math/computer science professor. He has a website and a blog, though I couldn't find the story online, at least not for free...
