From the time the human species became aware of their mortality they have begrudged the short time granted them between birth and the long dirt nap. To escape that eventuality a great deal of irrational thinking has been invested to create alternative narratives more comforting than that which reality offers.
Resurrection, reincarnation, magic elixirs, fountains whose waters grant immortality or sorcerer’s incantations - all delusions of the desperate to avoid facing the reality of death.
However, 21st science is circling tantalizingly close to significantly extending the 3 score and 10 that our genetics has granted us. Not necessarily immortality nor a single “elixir”, but rather, a combination of many advances in diverse fields: genetics, toxicology, immunology, pharmacology, nanobiology and others.
The dilemma is, would greatly extended life spans be a gift of science so desired over millenniums by human beings or would it be the greatest threat to human survival yet devised?
A group of atheist, I believe, would offer a more rational evaluation of the question than those with preconceived notions about the end of life and a mythic existence beyond.
