Every man over the age of 50 needs to do this every 5-7 years.. and it's a good thing.

Yesterday I had a colonoscopy and it was not bad experience. The preparation was the worst. Drinking a gallon of the "colon blow" (See Dumb and Dumber). It was a smooth experience for both me and my wife. Turned out no cancer; no growths. This is the best part.

If you are over 50 and and haven't done it yet, you need to schedule the procedure through your family doctor.
