Some see aging as a curable disease. I like this view so here are a few videos on how we might cure aging. Of course, curing aging causes all kinds of resource problems, but I still think we should be working on it while we are working on ways to generate clean energy, sustainable healthy foods and new living spaces. Perhaps some people who will live to 200 years old are already alive today. The trick, however, would be to look like you are no more than about 65 when you are 200 years old.
This should make me get out and exercise a bit more. It is the old dying cells sending out toxins and causing inflammation that does the most damage in your body, so there are ways right now we can combat that situation. See anti-inflammatory lifestyle.
