Randy, glad to hear you're doing well after the surgery and will hopefully be back at it again soon.
Regarding the weight loss, that is an amazing loss, even if it wasn't planned. Do try to make a plan to keep it off as once you're up and around, you'll be amazed at how much you'll notice it being gone. I dropped 70 pounds years ago (planned not illness) and it was life changing. Some of it has come back and I notice the difference and wish it was gone once again.
