Nah.
Nah, I wouldn't want to be able to extend my lifetime, because to be honest the only reason life is interesting and fun is
because life is short, if we lived twice as long as we do now then I think I'd kill myself, for example, life kind of dies out around 70, it gets boring from then on. So no, I'd stick with my own short life, short and sweet
Also, who knows what cost this extension would take? Fuck that.
