(or 2!) Dying of old age, can you actually DIE because of the body being worn out, or is it always a disease or such? I read that if we cure every disease, we would live hundreds of years.

Question

Title! I don’t get it. Isn’t my finger getting worn from just being used for too long? Or will it eventually get worse because of something else?

Answer 1

If you modify human genes to not age then we’re technically not human anymore. So yes, a new species could in theory be created to live hundreds of years but that species wouldn’t posses human genes in their current form.
