Old age, which is dreaded by all men, is to me the sweetest and most pleasant period of my life.

I found that a strict and regular life is the true way to conquer nature, and that the proverb which says that nature is so powerful is in part false.

It is certain that habit eventually has such power over human nature that it becomes, as it were, a second nature, and forces it to practise that to which it has become accustomed, regardless of whether or not it is good for health.
