Extending Life
Richard Chappell posted an article on his blog: Is Longevity Good For You? Here, I reproduce a comment that I had posted in response.
In my opinion, welfare is additive to the extent that it is consumable. The first step towards rational analysis of longevity is to realize that no matter how long an individual manages to prolong life, he/she is subject to eventual death. Personal welfare does not come into the picture after death, so from a purely first-person perspective, death is acceptable at any point of time. What really constitutes a measure of personal happiness is debatable, but this measure is something that cannot be defined beyond death.
As far as the social aspect of longevity is concerned, the stakeholders are both close relatives who are emotionally affected, as well as the rest of society that is culturally affected by the death of the individual, in terms of his/her potential contributions to society. Personally, I would prefer longer lives for my fellow humans, irrespective of the ‘shapes’ of their lives. My argument for this is two-fold. A longer life, with the exception of particular cases, raises the sum total of happiness amongst close relations. Secondly, the individuals contribution to society is proportional to the extent of his/her life. This is assuming that we provide the ‘elixir’ to everyone impartially. There may be anti-social elements whose longevity negatively impacts society, but they are in a minority. The same applies to ‘non-contributors’ to society.
In summary, life-extension research is necessary, because longevity is immaterial from a personal standpoint and beneficial from a social one.
