I'm not the original commenter, but as someone in a similar boat, I'll interpret:
Aging fucking sucks. Seeing doors close as your body switches modes is depressing as hell. Knowing you have another half century left, but it's all gonna be worse is a terrible feeling.
When you're 50 in the US, you have a little less than 30 springs left on average. a few more if you live in a country with a functional healthcare system.
Think about it: when you turn 50, you'll only get to say "summer is coming" 30 times. Merry Chrismas or Happy New Year to your family 30 times. Or "I'll do it next year" 30 times. And when you're 50, you know 30 years pass quickly.
And that's if the big C or COVID or something equally stupid doesn't get you first.
To the OP: enjoy your youth while you can. It'll be over before you know it. Trust me on this one.
I'm thinking I have 20 more years of being in working condition, so I'm planning to work less and travel more from next year already. Using my savings.
I don't dare to wait until I'm 65 to do all those things. Many people get sick and don't do anything.
Eh, I'm about the same age as OP, I don't have to get to 50 to know that I'd take my parents' economic context over the two crashes. The rest... For many reasons, if medicine does some miraculous leap forward by then, maybe I'll still wish I got a lot more left to go by then.
