Do you believe in this?
Honestly, as much as I fear dying a little, I fear getting old, old. If I could stay young and beautiful, it wouldn't be all that bad to live over a century.
Not so much as cybernetics as much as probably ingesting a substance that could extend a person's lifespan by maybe a few decades, but has to be consumed periodically in order to remain the way you are. Kinda like how Harry Potter has the Philosopher's Stone/Sorcerer's Stone or how He-Man had ambrosia or what have you. But even if you have longevity, you're still vulnerable, susceptible to dying of other causes, such as a gunshot wound that is fatal.
What do you think?
