Physical deterioration, the signs of aging, age related illness... All are more associated with oxidative stress/free radical damage much more than calendar time. We"age over time" because the oxidative stress accumulates daily in your body. But if you consumed enough cannabis... Cannabis as an antioxidant is the ultimate longevity plant. It's also why cannabinoids are being used to treat almost every ailment around. What isn't tied to oxidative stress? No one dies of an old age. They die from damaged and overburdened internal process. Separate biological age/health and calendar years from one another. Nutrition, lifestyle, oxidative damage is where the actions at on this one.
But no amount of Cannabis will prevent the effects of telomere shortening and nuclear H2A histone depletion.
