“Like Lou Gehrig, each of us is in a battle with our physical form. First, to master it and bring it to its full potential. Second, as we age or get sick, to arrest its decline—to quite literally wrest the life from it while we can. The body, you must understand, is a metaphor. It’s a training ground, a proving ground for the mind and the soul.”
