We can figure out how to better preserve our brains and/or put them in less squishy vehicles. That’s the only real path I see to significantly extending our lifespans, but who knows
Why would humans as a whole want to, though? Why would you, personally, want to? Is it just a fear of what might happen (or not) when you die? What do you see the goal being?
No animal wants to die. It sounds uncomfortable, but so is aging. As aging people always say, "it's better than the alternative"
