There’s some recency bias to that for sure though - silent and greatest generations were not as big on partying like x or the boomers. Of course things like smoking were more common but the heath risks weren’t as well understood.
But most generations before us also didn't have the same awareness about the health risks associated with a lot of those acts unlike younger people today.
And the generation after us will probably think we were dumb about stuff as well (eg. social media, disinfo, Delta9, etc).
