"It is a very wise rule in life not to be too anxious about health, or to be entirely free from the inconveniences and bodily ailments of old age. It is far better to submit with patience to what is merely annoying, but does not altogether confine us, and still better to treat with indifference the uncomfortable feelings which such a state of body calls up."
