There's a reason we ensured all of our kids were potty trained by 12 months. Forgetting about that aspect of life is a wonderful thing.
Tim, I still have to cope with the unaesthetic aspects of it, personally.
I had a total colectomy in 2001 because of severe diverticular disease. No precursors, so almost certainly genetic. About 3 feet of redundant colon (9 feet long, instead of the more normal 6-7 feet).
No ileo-caecal valve left, and about 25cm of large intestine left. Fortunately, not a colostomy. My surgeon was at the height of his skill when he fixed up all the problems in my abdomen - apart from the above, I had holes in the omentum, adhesions from the appendicectomy when I was thirteen y.o., two anastomoses joining the small rescuable part of my large intestine to the end of the ileum and the top of my rectum.
Brutal, meat ball surgery. I live with the consequences every day.
Fortunate to have it when I did. Two years later, I had open heart surgery, and on Warfarin (or Clexane), so I would never survive that surgery after the heart surgery.
I'm very fortunate to be alive.
Puts all my other health issues into perspective ...
