When I turned 50 my doctor set me up for a colonoscopy. Five years ago they found a non-cancerous pollup which was removed immediately but the doctor wanted to see me again in 5 years. Fast forward to today. I had my second colonoscopy this morning and all was clean; they found nothing. I still need to have the procedure every 5 years due to a history of colon cancer on my dads side of the family. I cannot express the importance to all you guys out there who are putting it off; it's no big deal. Heck they put you to sleep during the procedure, you don't feel a thing. The only side effect is the gas that follows. Man, I swear I went air born a couple of time. If I could find a way to bottle it, know I could heat my house for a year with it. Roger
