I didn't have a problem turning 40 this year. I've believed, like most, that because we waited longer to get married and have children, essentially doing everything our parents had been doing in their 30's, that we were a young and vivacious as our parents. I had no concerns - only celebrations - around the black "over the hill" day.
That all changed at my last OB/Gyn appointment. Chatting with my doctor, she gave me the requisiton for a mammagram. "Now you're old enough to start going to these lovely procedures," she congratulated me. Whoa! I suddenly realize the obvious.... can I really be THAT old....shucks.
