I only concern myself over the things I can control.
I follow the scientists that are working on reversing the age of cells. Currently the human trials are only working on specific body parts, but in a few years it may be applied body wide assuming no major issues come up. The most promising work I am following right now is by Dr. David Sinclair and his team at Harvard. [1] There are many teams in numerous countries working on this and similar techniques.
In the mean time, I avoid things that cause premature aging and do what I can to reverse damage from the western diet I had eaten for so many years.
