The trend which started long ago shows few signs of abating. Life extension is not a new concept. In a sense, the entire field of medicinal research directly or indirectly promotes the extension of human life. There is little doubt that science values the idea of enabling people to live longer. In other words, he would like to live long and prosper, physiologically and materially, which of course would enormously enhance his happiness.
Longer lifespan seems an obvious value.
It is hard to imagine anyone considering it a negative. Yet, some do. This fear about longer life being a burden rather than a load-lightener has a distinctively statist origin and appeal. Historically, in the more barbaric states, the elderly have simply been killed off. As we all know, many nations have mandatory retirement ages and ages beyond which citizens are unconditionally entitled to government welfare.
