As an individual in the present, no.

My initial thoughts are that extending human functional/contributing, life span by multiples of the present norm would only be beneficial in a global culture adapted to the same. Much like our current societies have developed in the last two centuries to accommodate and utilize a life expectancy of more than two score.

My second consideration is that the concerns held by many, of the planets capability to sustain the current population, let alone a MORE increasing one, is inadequate. Under the best of circumstances, it would require a Plato's Republic to function in any manner.

Now just bend over and I'll explain the benefits of TODAY.
