In my early 20s, I got tinnitus even though in the rare occasion I’m around loud noises I wear hearing protection.
In my mid-late 20s, my vision got worse after never needing glasses and my knees starting creaking with occasional pain. I now need some more involved dental work even though I brush and floss regularly.
I’ve lived a predominantly outdoor, active lifestyle the last several years, so I should be quite well off health-wise, but it still feels like I’m aging faster than I should be. wtf?
I am 60 and felt fine into my late 30s, and even then the changes happened slowly. Our world has become more toxic, and you are suffering the direct results. Some are luckier than others, but you are correct that things have changed for the worse. Plastic is a likely main contributor but there is a lot more crap in your environment than there was when I was 20. It breaks my heart that it should be so. I hope the future has some remedy.
