As usual, immortality is the solution.
I’m not sure if you’re joking or not but many people are not when they say this.
Immortality is impossible in this universe given known physics. The use of the word is at best equivocation and a rather desperate self-delusion. Even if we ignore physics the probability of dying by murder or suicide trend towards 1. All of us are contingent and will eventually face our death.
Are you prepared to bet on this?
We have a bit of time to worry about that if we manage to get rid of aging though, I'll give you that !

"Biological immortality" is an equivocation. Immortality is not dying, "not aging" is not immortality as, for instance, those jellyfish definitely die. Even if we stopped humans biologically aging and cured all diseases the universe will still find a way to kill us even if we sidestep all the causes until the universe itself dies of heat death.
