The second myth is, there are treatments that can help slow, reverse, or even stop aging. False. When you think of it, there is 99 things that can age us. Deprive your brain of oxygen for just a few minutes, those brain cells die, they never come back. Play tennis too hard, on your knees, ruin your cartilage, the cartilage never comes back. Our arteries can clog. Our brains can gunk up with plaque, and we can get Alzheimer's. There is just too many things to go wrong.
