Each night, as I prepare for bed, I put drops in my eyes to fend off the threat of glaucoma that would rob me of my sight and take from me the pleasure of reading. Each morning at breakfast, I take a pill to control my blood pressure, and each evening at dinner I take another to lower my cholesterol level. But instead of lamenting the ailments that come with growing older, instead of wishing I were as young and fit as I once was, I take my medicine with a prayer of thanks that modern science has found ways to help me cope with those ailments. I think of all my ancestors who didn't live long enough to develop the complications of old age, and did not have pills to take when they did.
