Part of a short collection of medical advice, Spiesel reports that long-term studies show LASIK eye surgery is largely successful, with no evidence of health complications -- good news for the 18 million people who have undergone the procedure. The most surprising tidbit of the piece: Sugarless chewing gum can cause diarrhea. But the big question of the week is how to live a longer, healthier life. Spiesel responds with a four-item checklist: more exercise, more fruits and vegetables (five servings to be exact), less alcohol, and no smoking -- not astonishing advice, but its simplicity counts for something.
