Sir Arthur C. Clarke predicted that humankind would achieve actual physical immortality. I don’t think we can reach that goal on Earth, but we are living longer than before.
Biology does not cooperate with Sir Arthur’s prediction, so far.
Researchers want to extend the lifespan of people, however, to at least 150 years and one obstacle they face is how to persuade cell division after age 113, on average, without death or cancers associated with that additional cell division after the cells’ telomeres are used up. Telomeres shorten at each cell division and they have only so much length, then the organism malforms or dies.
But, how old would you like to be?
If you live to 150, it is almost sure that you will need some replacement parts – but we do have them!
We may even be able to refresh your brain.
