You make a very good point about social media today, gettingon. That is one of the major differences in life today as compared to when we were all young - and why, if I were a young woman now, it might not be easy to live my life in quite the same way as I did then. As I said upthread, it is not about having regrets about what we did and didn't do, but about how we would live in today's world.
I do wonder, for example, if I would get married as young now - not only because I might choose differently, but because the expectation that a serious relationship almost automatically leads to marriage is no longer the case today. So I might well be in and out of relationships today, not settling down till my mid thirties. My entire life path would be different as a result.
