I hear ya Doug. Exercising and eating a whole-food plant-based diet has made a huge difference to me in postponing the inevitable. The diet thing can't be understated (cholesterol went down to 130 from around 200). No statins or other meds and no aches or pains (if I take a break from core-exercise my back aches return). If you have an injury (of course) all bets are off and you may be limited on the exercise. Otherwise no excuses "getting old" is not a disease it's only a factor, but there's no pill the doctor can prescribe it's all in our hands: Eat the standard American diet of meats/dairy and processed foods high in fat/sweet/salt or overindulge in alcohol and you kill yourself slowly, and yet the doctor will say you're "just getting old". But your condition is reversible. Coronary artery disease, and autoimmune diseases, (Type 2 diabetes can be
reversed in 2 weeks, Rheumatoid Arthritis, IBS, "acid reflux"and more) many types of cancers can be prevented or reversed. The way I see it, we're in training for the rest of our lives. You can make a decision. Do nothing and the inevitable comes sooner.
For anyone who thinks this is wishful BS there is a mountain of scientific evidence to back this up. Watch FORKS OVER KNIVES on Netflix or Amazon Prime. And go to
