Jonni, I am 68, also retired, and just beginning this journey, too. I am on Medicare, and must go through several months of different types of counseling prior to receiving a surgery date. Like Elidh, I realized I wanted to improve my health to enjoy those retirement years. Some days I think about the foods I will eliminating from my diet; and then I realize, it's the very foods that have lead me to this point of overweight-ness, and which is more important to me - those foods OR my health, for heavens sake?!?
Good luck with your procedure; look forward to following your positive progress!
