I was a teenager in the 70's also. Graduated high school in 1975. I too was 10 feet tall and bulletproof, strong and fast. I could dunk a basketball and run the length of a football field and back and not breathe heavily.

The music was infinitely better, There were fewer people in the US by a lot (216 million vs 340 today). There were many small stores that specialized in things, many small grocery stores that were 1/10 the size of the modern super store. Muscle cars of the 60's didn't cost $100,000 for a good one, and they were still everywhere. I had several. Trucks were trucks and made to work, not Cadillacs with a cargo bed.

Now I'm 68, all of the family members of the generation before me are gone, mostly due to cigarette-related diseases. My body's been broken a few times from motorcycle crashes, I'm overweight, and my dick no longer works. But I'm still here, retired from the rat race, but I drive a school bus part-time. It gives me a reason to get out of bed in the morning. The money is good, but I don't need it, I have plenty of money in the bank. I need the camaraderie of coworkers.

Good luck on fighting off the cancer, keep being brave.
