Hi there, and
Hey, there ARE a lot of us. And you're welcome to join in. A few spots you may want to check out...first, we have the 40-somethings, for those in your age range. We also have a Calorie Counters forum, if you're still following a BL-like calorie-based plan. We have forums depending on how much weight you have to lose, too, from the "Featherweights", for those who are starting relatively close to goal, to the "100 lb Club", for those who are on their way to losing or who have lost 100 lbs or more. And all kinds of miscellaneous groups, challenges, etc. So look around and jump on in wherever feels right.
And if I read your post right,

Happy Birthday to You!
I'm glad you've joined us and I can't wait to get to know you better!
