I've always had a fascination with longevity. Some animals only live 24 hours while some plants or animals can live hundreds of years. It's been theorized that people could live to be 1,000 years old if the major diseases could be eradicted and oxidative stress damage (basically cell damage) could be halted.
Do you think people will ever live to be over 200 years old? Over 500 years old? Longer?
Would you want to have an extended lifespan if you were protected from disease and the effects of old age? Would you want to live forever if possible or do you have religious, ethical, or other practical purposes for objecting to it?
I want to write a book about what life might be like if people didn't have to die and would like other people's input on the subject. Maybe you can give me other possible ramifications that I hadn't considered if such a thing were possible.
Personally, I'm afraid of death so I'm all for anything that can lengthen the lifespan. However, I realize that nothing lasts forever so solving one aspect of human mortality only opens up a whole other can of worms. According to scientists, our sun will eventually turn into a red giant and destroy the Earth so we'll only continue living if we find another solar system to move to. We'd almost have to move to a new planet anyway if no one dies because the Earth would get overcrowded quickly. Plus, how might social change be hampered if old generations continue on indefinitely instead of eventually being replaced by new generations?
