Not at all. I have always found far greater interest in the mental than the physical. Which is to say, not only is it the subject I am more inclined to research, but as well what I value in myself and others. If one were to attain eternal youth, though he may cultivate a great number of experiences, that life would not be so rich as one lived to old age. As I see it, it is in our change, and the briefness of a lifetime, which makes each individual life truly miraculous and beautiful.
