Some of the advice presented is just good sense-- eat right, get enough sleep, exercise.
Some advice is, well, just plain strange: Stopping your periods through yoga, "The Herbal Fountain of Youth," using Peelu Bark instead of toothpaste, preventing breast cancer through massage...
Really?
There are several plugs for herbal supplements, including Dr. Chang's Forgotten Foods "Female Formula: BD-203, Reproductive Tonic Combination," which "strengthens and balances the female reproductive organs and hormonal system."
The one that really freaked me out was the recommendation for daily herbals, including Hawthorn for the heart: "Scientific evidence shows that it is beneficial in cases of mild heart failure."
I like the simple exercises, but then Berns brings in the bizarre. Two words: Prostate massage. Eww.
I have no doubt that JB Berns is an excellent advisor on the martial & yogic art, as well as a great personal trainer. I think that following a healthy lifestyle-plan is extremely beneficial.
If his methods work for you, more power to you.
I'll stick with the trampoline based Berns exercises & leave the book to the brave.
