I'm almost 40, and I think I got the answer, but the answer is never one-sided.
If you don't want to grow and learn from life, it doesn't really make much of a difference whether you die at 17 or 75. Sure you'll grow a bit anyways but not enough to find a better life if you don't seek it. The more effort you put to making your life better, the more pain you'll face, unless you're smart about it = find yourself and be yourself beneath all that conditioning and all the other bs. Running from pain and resisting it will make you fail and progress stops, you gotta face it head-on at some point. Sometimes it's too hard and that's when you need to run from it, if you wanna stay above the water.
And pain's not really important, but what the pain and other senses are telling you about yourself and about the world.
We all have different extent of challenges, and we're defined by how we tackle them. If life is a fight and you don't wanna be in the ring, you can quit, but there's no guarentee you'll be let back into the ring again. And the fight's never over until you die, not the fight inside you. Outside you, sure, they can lock you up and do anything, but inside you, no.
These days we have the internet and all kinds of knowledge accessible to us. It may be hard to trust a lot of it, but experience and honing your senses will be your best guides when searching for your personal salvation. Anybody can finance and control any info with the money and power if they really want to, but your own experience will never lie, it can only be misinterpreted, and often is too. You gotta have the bravery to test things yourself if you want to actually find your things, things that make you feel like life's worth living, and stick to them for more than just one time and put some effort in them so you see them in their true form instead of a shallow reflection of what they really are.
At least, that's how things worked for me.
