This is a book that helped me direct my life. After recovering from prostate surgery, I was looking for answers. I found some in this book.Although many readers may not consider their guidelines profound, I have tried to adopt their advice about exercising much more and eating better. Exercising six days may be a little much, and not ever eating crap is not quite my style. However, I did run two one-half marathons this summer, and my previous longest was 10 miles - back in 1980.I am younger this year than last.I also recommend its bibliography.
