Being the beneficiary of a twice repaired back, two prosthetic knees, two prosthetic hips, one repaired 100% separation/torn rotater cuff and one kidney stone removed from my bladder, it's kind of hard to get me to badmouth modern medicine. I'd be an invalid instead of being able to ride a bike and walk 18 holes of golf. And being an invalid is the kind of thing that will kill you.
You probably won't hear Janet doing so either, especially now that she has 20-20 vision in both eyes after cataract surgery. Which is better vision than she ever had as she started wearing glasses at age five.
