I'm in my mid-40s and don't have kids. In the last 5-6 years I've gone from figuring it'll be ok-ish in my lifetime but will suck for the next generation, to legit wondering if life will be a complete hellscape by the time I'm a senior citizen. And more important, what if anything that means in terms of how I live the rest of my life. For instance do I live life to the fullest now? Or do I skimp and scrounge now to have some hope of surviving when things really go sideways.
I hope that it's just doomerism on my part, but the fact that someone like myself is already putting mental energy towards this does say something in my opinion
