One thing that strikes me as odd when I look back on my dating history is that there was a period of time -- I was in graduate school at Wayne State in Detroit, which offers graduate degrees but doesn't have a graduate school in the sense that the Ivies do -- when I just didn't meet any men I found interesting enough for one date.
During that period, I had a great many male friends who were married (or had committed girl friends) who truly liked me. Whenever they had a former college room-mate or relative come to town, they would ask me to go out with these guys because I was the only woman they knew who was literate, liked jazz and psychedelic rock and folk, went to movies and the theatre.
I had some great dates this way, but there never was any physical chemistry on my part. I tend to think there usually isn't with blind dates. What people need is to see each other. If there is physical fizz, there is! Of course, that may be the reason for the high divorce rate: too much fizz and not enough substance.

Recently met a man at a singles event sponsored by my one of my alumni associations. I swear the guy hadn't been to the dentist in 30 years. Deal breaker!
