Iv noticed this also. Especially in regards to physical activity. Iv worked with a bunch of younger guys the past few years and I'm always trying to encourage them to get into weight lifting or boxing ect. Even wrote a couple workout programs for em.

It stuck a few times, but those are few and far between. I think its in part because of the whole instant gratification our society is now used too.

Primary cause is microplastics OP, that mimic estrogen in the body. It is done on purpose? That you have to show the work on.
