I don't go into great detail about health issues because a) I don't want to bore you with my problems, and b)I don't want you to feel that you have to share YOUR problems in return. But this is important, so I'm putting it here.
If you are 50 or over, I strongly recommend a colonoscopy.
I had one this past Friday, and would go on in odious detail, but Dave Barry has gotten there first, and is much funnier about it than I would be on the subject. My experience is similar to his. In my case, they found a single (huge) polyp that appears benign, but they are doing a biopsy on it and I should know the results in a couple weeks.
This is a serious major step for anyone in regards to managing their own health (and that would be ... all of us). Colon cancer is the 2nd major killer of men in my age group (and third for women). The procedure is time-consuming from the standpoint of preparation (see the Dave Berry article), but is outpatient surgery and was handled professionally and (yes) painlessly.
This is a case where silence IS deadly, so pay attention and check with your GP.
More (hopefully less of a buzzkill) later,
