Dr. David Sinclair believes aging can be slowed or even reversed. He is a professor at the Harvard Medical school. There is much information about him and his research including 120 is the new 80 and more.
As with anything, from idea to finished product can be a long road and I am thinking if there is any likelihood of this happening, it may be some time away.
