WarriorDad, keep working and stay focused! Recovery from surgeries like you've had take their toll, but determination, clean eating and moving (exercise/cardio) go a long way to staying young. When they diagnosed me with severe bone/arthritis issues many years ago I let it rule, the meds were too much so I threw them out and went back to what I knew running and training hard. So this year when they diagnosed chronic liver disease and a form of bone marrow cancer I was able to face with renewed determination. Granted the prednisone treatment slowed me down, but I've again thrown the drugs away and focused on clean diet, training and competing and its actually keeping the docs off my back! If you need a kick in the seat give a yell...
