I am 65, not over weight and do a restorative Yoga daily as well as teach it. I also do a
Yogic breathing practice daily that
is an immune boosting simple breathing practice. I have not had any illness (except the Fibro) in two years. Because of the Fibro I have changed my lifestyle in regard to sleep (I get 9 hours) and diet. (I do not eat fried foods, soy, peanuts or dairy.
