BIkram Yoga for me about 4 to 5 times a week. It is 90 minutes of intense exercise in 105° room. It kicks my butt every time I walk out after the routine. I have been at it for about 4½ years now.

Other things that really help:
Surfing (Californian after all)
Bicycling
Sailing (as many as three days a week)

Eat only or mostly organic foods so you do not put too many poisons or unnecessary hormones in your system. Drink lots of water.

Eileen is giving me a 50th birthday present of spending a month in Europe including sailing in the Formula 18 Worlds and the Tiger Worlds. We had to figure out how we were going to keep up. This is it.

Later,
Dan
