What does I think mean when a guy is curious about your age?

Anonymous
There is this guy that's really good looking, he's probably in his 40s... I have a light feeling that he might like me and well i like him.. Anyway, I have noticed that he always treats me a little different than he does with other girls, for example, he listens carefully to the things I say, he always greets me and he tries talking to me all the time and does it with a very respectful and caring tone (which confuses me because I don't know if he is been just polite or if he might like me). Lately I have noticed that he is always bringing up subjects that may push me to reveal my age. For example, he keeps saying that my way of fashion taste is very lady like for a young woman, or my taste for old music is too old for my age, or that I'm very mature for my age... which leads me to wonder why is he so curious about my age?

Guys, gals out there, any ideas?
