This is an article from 2004 but, since most people dont know about this subject I decided to post this.
There is research being done to reverse aging, and make people young virtually for ever. Cambridge scientist Aubrey de Gey, says some people living today might benefit from this technology. He is the leader in the reasearch in this area.
In my opinion this is the most important technology to develop, and I think there should be much more investment. Wouldnt it be wounderfull if we could see our people reaching the stars???
here is the article:

Other inetresting concept about this subject is Cryonics (preservation of the body after death to reanimation in the future when technology is developed enough). Alcor is a company that does this.
