Free warning: I spend a LOT of my waking hours in front of a computer, either working, playing, or informing/educating myself about the world around me, which I am half-convinced is not virtual. Ask me about the proportions, if you care. Ask me about the proportions before I got a good career and lost a long-term girlfriend, if you care. Ask me how much time I would spend in toto after finding the right person, and I will not only answer honestly but admire your moxie.
I do biomedical research, which isn't nearly as glamorous or as useful as it sounds. Ask me what proportion is actually wonkish, useless, viciously selfish, or purely political/expedient, and I could come to like you.
I am the man (da MAN, if you like) when it comes to giving backrubs, discussing socioeconomic issues, washing dishes, losing at racquetball to men twice my age, or ragging on tennis players far more talented and dedicated than I'll ever be. Ask me which of those is the most enjoyable, if you like, but you canNOT be serious! When it comes to skill, backrub is the clear winner.
I am usually wearing some horribly unstylish synthetic-fabric vest or hat. Not to mention the general unstylishness... Ask me if it's because I went to grad school in Seattle, and we don't know any better; or because I can't afford fashion; or because I aggressively pretend not to care about fashion because I suck at it.
I read a lot of different stuff: classics such as Twain, even the stuff from his old and bitter phase. Pop science such as Steven Pinker, Jared Diamond, and Brian Greene. Eloquent polemicists such as Richard Posner, Paul Krugman, Jonathan Chait, and, well, excuse me, but Ann Coulter, who is not only entertaining but positively enlightening once you realize she's essentially an attention whore who will say anything even tangentially conservative in order to boost sales. Science fiction visionaries such as Neal Stephenson. Speculative purveyors of "cool stuff" such as Steven Brust. Any military history I can get my hands on. The consummate master of oratory, George Orwell. Any unifying thread would have to be that I require eloquence and not mere competence. I am willing to forgive a clever and engaging writer who has nothing to say, Wodehouse being a good example. But I cannot condone mediocre writing, even in the service of good material... and no, I am not dumb enough to name names. Anyway: ask me which I read for pleasure, which I read for fun, and which I read just to impress people.
Conversation Starters (i.e. what you'd like to do on a first date...)
Very traditional: dinner, drinks, some form of cultural event: readings, book signings, museum visits, live music (preferably classical, but I will always do jazz or local rock bands too), plus a late-night visit to a dessert or coffee place to get a chance to really talk.
