Young people really feel a lot of pain as do older people who have more time to get used to it, and I have found that I always hurt and the best I can do is to sit in a chair, even sleep is painful and I think that everybody else and even maybe everything else has this kind of pain, like the fly in the basement probably has arthritis, and a Zen master once said "Even if you get to the very bottom of Zen meditation, there is still suffering" so oh well, no pain, no something or other.
