I am in the process of getting certified, finally, at 43 years of age. I have been "waiting" until I looked "good" in a bathing suit/wet suit... I finally realized how much I was missing! I've decided to just FORGET the weight issue and learn to DIVE! I've loved the pool time, and this weekend will be my open water beach dive!! YIPEEE!!! My future daughter-in-law is taking the class as well.. and she is extremely thin.. and is cold, cold, cold, even with 11mm wetsuit! I was quite comfortable! I'm glad to hear that others are of my size, and age, out there diving too! Oh, this is my first post to the board also...
