I just went through a Once-Over-Lightly physical exam--BP, cholesterol, muscle-tone, body-weight, and so. The people in the white coats reviewed my veggie and iron-pumping lifestyle and so forth, and agreed that if I was careful crossing the street I would probably live forever.
This will probably be a great comfort to my late father who was himself planning on living to a hundred. It really pissed him off when he didn't quite make his goal which was three years short...
