I´m 31 and blush sometimes. If it happens at work, I hate it. There is a co-worker, and it seems to be a learned behavior that I blush if I see him all the time. I think its because I blushed once when he was in the room and now it happens always when I see him. I hate it. He probably thinks I like him. Well I do, but there is no f... reason to blush. Or it happens at a Restaurant...and I´m there with my boyfriend and there is a cute waiter. I think that my boyfriend thinks that I find the waiter attractive, and this thought alone makes me uncomfortable, because my boyfriend is the only one for me! My boyfriend will ask me why I blushed, and I reply with, its kinda hot in here ...haha...it´s a freaky mindgame I wanna get rid of!!! There r situations when I expect to blush but I dont, e.g. in front of a class for a presentation. Maybe more interaction with people will help, to "train" the brain to be more relaxed...
