First off let me say sorry to hear your thinking of giving up the drivers seat. Second you might not like, have you gave up those cancer sticks yet? I hope so. I just came back from the hospital , visiting my younger brother [ 52 ] who is in there for respiratory failure. He now has a trach in his throat, on a respirator to keep him alive and can't talk. He wouldn't stop smoking either. I know it only happens to the other guy
