I would say 80%+ of men in the west do not have the discipline and willpower to exercise routinely and eat cleanly. I'm continually surprised at grown men who don't eat vegetables and fruits simply because they don't like them, like a fvcking 5 year old. Sloppy living begins to show at 30 and beyond.
Other unhealthy habits, like drinking, become more routine. Weekend drinking bleeds into weekly happy hours, then bi-weekly happy hours, which bleeds into a beer after work Monday-Wednesday, which becomes a few beers, etc.
The unfortunate "athleisure" fashion trend of our millennial cohort, solidified by Covid, has been growing in recent years. You won't catch me dead wearing sweatpants except in my apartment after work or on my way to the gym. However, it can be appealing to women since it signifies that you're athletic and in-shape. Of course, provided you are actually athletic and in-shape.
