That was my reaction too. I mean, no one likes to die but if we look at it objectively - death is one of the very effective ways in which society changes from old ideas to new ideas. In a hypothetical scenario where every generation lives till 120, I would assume that current US congress will probably continue with the same members for so long (if you notice, most of them keep getting re-elected so many times). And that would mean no infusion of new ideas. It would also means abolishing of social prejudices like slavery, child marriages etc would have taken a lot longer.
