Everyone wants to live forever. Or at least, avoid old age for as long as possible.  And while anti-aging research is rapidly advancing, so far, longevity drugs have yet to cross over into the realm of human medicine. In other words, the only ones who get to use them so far are lab rats. Spry, youthful lab rats.

But all this is about to change. What's on the horizon for life-extending medication?  And how long will it take until you can get your hands on it?  Watch to find out.
