The most important factors for a long life, I think, are partly in the genes; number two is lifestyle, which includes healthy diet and regular exercise. I walk, run and swim every day. However, I think too much exercise is also unhealthy because of over-stress; sometimes people who exercise too many hours per day die early.
I played the piano as a boy for six years, from the time I was six to 12 years old. My piano lessons ended when my father died because our family had no more money. I used to have a mestiza teacher. She'd come once a week to teach me piano lessons, and she'd bribe me each time with an apple; otherwise, I wouldn't play.
The important thing to know is that life will always deal us a few bad cards, but we have to play those cards the best we can. And we can play to win. This was one lesson I picked up when I was a teenager. It has been my guiding principle ever since. When I wanted something, the best person to depend on was myself.
Of course, the most important factor of all for long life is a good family. When a person goes home with the wife or the kids giving him endless headaches, then it's hard for that person to enjoy a long life. I am very fortunate, because my wife Elizabeth and my obedient children are very good; they have given me happiness.
