I am almost 47 years old (in July this year).
As for a lot of the crap that goes on of late vs a lot of the crap that went on in the 2000s and early 2010s, it does seem that over the past decade or so many people have simply become more blasé about a lot of things that many previously expressed greater indignation against.
I can't really decide as to whether it's a good thing or a bad thing, but it does seem that the UK (at least) reached peak 'moral panic(s)' and the like in general during the 2005-11 period, as I pointed out upthread. And most of the teenagers I tend to notice these days whilst out and about generally seem to be a lot tamer and less boisterous compared to back then (and also back when I was a teenager myself), even though they will always still be the odd exceptions of course.
