"Practicing what we preach is not always easy. Those of us who are service-minded often put others ahead of ourselves. We go too long before getting the oil changed in our cars and reschedule or cancel appointments to accommodate others. I’m guilty. My doctor hounded me for two years to get a colonoscopy. I dreaded it for lots of reasons. However, in the end, all the worrying was unnecessary. Yes, the prep isn’t great, but it wasn’t horrible. The hour-and-15-minute ride from my house to the facility was fine, too. Even the anesthesia, which usually makes me violently ill, did not make me even the slightest bit nauseous. I received my results immediately. I’m good for another 5 years — one less thing to worry about.
