Since it seems to be the most common deal-breaker I'll address that I am legally married to a wonderful woman. She is well aware that I'm on OK Cupid and thinks it's very funny. It's as awkward as you want to make it, which would preferably be not at all.
I am a traveler. I have been to approximately 40 countries and almost all of the states. I just got 82 more pages sewn into my passport and intend to try to use them all before it expires.
I also have a fairly mundane daily life to support that habit. I have a 40-hour a week job that pays the mortgage on a quirky old house on the near-east side. I garden and perform amateur electrical work. I sleep about five hours a night and haven't called in sick in over a decade because if I'm going to feel awful I'd rather get paid for it. I'm a Madison native but I've lived in Seattle, Denver, and Reimst. I'm spitefully knowledgeable about international law and my political beliefs don't conform to any party I've ever seen.
Honestly though, none of that is too important.
