I'm 40 now what???????????

I read all of these posts and the average age seems to be the 40s. I just turned 65 on 8/30. Sounds old, but now that I'm here, it really isn't. I remember the surprise birthday party for my 40th and it seems so long ago. I'm looking forward to many more years being a lot slimmer than I was at 40. That the good news. Enjoy your years, they go fast! Marilyn
