I have been reading up on Taoist techniques for rejvenating the blood and bone (Bone Marrow Nei Kung by Mantak Chia) and have got me wondering some things.

According to the book above, fitness athletes and bodybuilders etc train so hard to achieve high fitness levels and always aim for the best nutrition, yet still only live just as long as the average person.

The book says that the reason for this is the rest of the body gets so overused that the organs have to give in someday. Meaning that the person/athlete in question can achieve perfect muslce and nutrition, yet still not improve his/her organ system/blood and bones.

It all seems to make sense to me (to an extent), but i am sure the Tao exercises written in that book arent the only ways to rejuvenate the organs/blood/bones in order to achieve perfect health.

I would love to hear what other have to say regarding this. How much do you agree with this? And would you know of methods of internal organ rejuvenation other than of the Tao?

PS: The book i have warns to not try the exercises without an instructor of the universal Tao, otherwise it is at the readers own risk and may cause severe health problems and even be fatal???
