I just wanted to echo what others have said - you have done something amazing! Since you lost it fast, I would say give it some time. Skin can take some time to adjust - and add weight training as others have said. If the boobs bother you, I don't think your age should be a limiting factor if it's what *you* want to do for *you*. You're active, you're in great shape - do what it takes for you to feel that way. I don't think you need to settle because you're 56!
