Daily weights are seldom accurate because no one pays for them. Chronic complainers, hypochondriacs and Munchausen patients can contract the same diseases as everyone else. The most underrated piece of medical equipment is the fax machine. American hospitals have 19th century record keeping systems because they spend 19th century dollars on the problem. Not charted not done.
Doctors make the worst patients.
Doctors' relatives have the most complications. Doctors are lousy investors. Only nice people get cancer. Nasty people don't get bad diseases. See one, do one, teach one.
