Hehe, I know what you mean about the funny looks - it seems to get worse when you're older.
Last summer I was working out and some people even stopped to watch (not that I was doing something that particularly spectacular, seems like they were more like "what is this old guy doing").
Then it gets all weird cause you feel like you have to impress... haha
Unfortunately, I haven't trained since then.
Wish I had the chance to go out and do some sprints, it gives you so much energy for the rest of the day.
