Jedi-
I think my dad was 83 when he spent three months with a 'bag'. I really had to hand it to him. He never complained, and was still his friendly, humorous self. I'll bet he was happy when it was reversed, though. It's a great reason to remind men over 40 to get a look-see every two years.
Glad to hear he's okay.
(technical note: it's colonostomy. Colonoscopy is the inspection procedure, using a sort of flexible borescope like a mechanic would use to look inside of an engine.)
