I'm much better in bed now at 59 than I was at 19 or 29. Experience matters, yo!
And yes, the fact I've seen every thing that people get into a tizzy about today come and go five or six times in my life makes me far less likely to jump on bandwagons I've not already been on for decades.
The first time someone stood up in the subway to offer me a seat was a rude shock, but since then I've come to like it.
