Weight-bearing exercise builds bone density builds your muscular strength so that you can hold your body up where those bones have a tendency to get weak.
Certain kinds of speed flow intensity density of attacks density of interaction... Music that concentrates on those qualities is I think easier achieved by free improvisation between people sharing a common attitude a common language.
I became much happier when I realized I shouldn't depend solely on my career for my sense of self. So I developed other interests and surrounded myself with a small group of friends I could trust.
