Explanation: Plumbing back up malfunctions are a lot more stressful and dangerous to the system. This 80 year old's are funcioning and even doing well only once a day instead of continually. Little problem with clean up but, what the heck, can't have it all!! At least he sure sounds like he sleeps well!! No tubes and a sense of humor! Doesn't sound like the worst of the 3 to me. Caroline
