Even here in Britain, curtsying has largely gone the same way as bowing and tugging the forelock, which is to say you don’t see it happen all that often, though that perhaps speaks more to the circles I run in than wider trends.
However, even though I rarely have the opportunity or inclination to show respect to my social betters, I have been doing a lot of curtsying of late, because the curtsy lunge has become a fixture in my leg workouts.
