Can Humans Live Forever?
Knowledge of our own mortality can be one of the largest fear-provoking thought exercises and motivating forces. One way this motivates scientists is to try and solve the riddles of aging, and the once science-fiction idea of immortality has become something that may actually be in reach.
If any of this is interesting to you, then take a look at this recent piece from CBS news on the advances in aging research. If some sort of procedure ever actually makes living indefinitely possible, it will be quite interesting to see how people make decisions regarding it.
