Downvoted not because I’m afraid of my own mortality, but because pointing out the obvious fact that nobody can see after they die is neither insightful nor useful. Go tell that to someone who has become blind and let me know how much consolation that provides them.
Even if I knew was going to die tomorrow, I will not exchange my remaining eyesight for qudos. I would prefer to spend my last day looking at my family, the trees, the running water, the flowers. It seems totally uncontroversial to me, I'm really surprised to find someone who disagrees.
Sorry, no, I just meant that the maximum human lifespan recorded so far is 12.2 decades, and the vast majority of people reading this will die in even less, 2–5 decades, regardless of what happens with climate change. Given that, it's silly to treat your body as if you could make it last forever.
