Exactly. The naively delusional notion that things get progressively better is completely laughable, and in all honesty, insulting. The passage of time does not make us younger, better looking, or increase our chances of success — the opposite is the truth. Every single day that passes is yet another day added into an ever-growing list of miserable, desolate, and wretched days in our lives; days that could have been spent in meaningful joy, making memories if fortune had graced us, instead, they were spent devoid of any of those things.
The more time that passes, the more devastating the missed milestones become; time cannot be reversed, and the damage cannot be repaired. You grow bitter, jaded, and more miserable with every passing year that you spend on this earthly plane — and the older you get, the more it hurts to see those far younger than you lead lives of wanton pleasure, completely unaware of the daily torment that grips the very essence of your being.
You look in the mirror, and the only difference is that you are uglier, and the youthful light that once brightened your skin — even if your life was miserable — is gone. Your hair thins and begins to erode as you inevitably start to lose it, turning you into an even bigger subhuman. It doesn't get better. There is no light at the end of the tunnel. Nothing to look forward to.
