the pill of life?!

heard on the radio one piece of interesting news (and it wasnt another election row, for a change!) that scientists are in the process of developing a pill that prolongs your life for 30 years. they said sthg like u hav to start taking it in your thirties, and presumably you'd live til over 100 years old, but they're only at the mouse trials stage. hmm, how dodgy is that?! not sure if i can believe it would work.. LIFE itself reduced down to a little pill!! craaaazy...
