45.
There's a cute story behind it though.
When I was 20, I was on the train and this man saw me through the glass and because the train was still moving, he ran to my door to come sit by me. After making conversation, I initially thought he was 32 or so. Turns out he was FORTY-FIVE. He aged VERY well. Anyway, we kept talking and we walked to the subway together and he held me under his umbrella (still makes me blush), went on a few dates but nothing came of it. I don't really care about age even if he was my parents' age.
