Take your point, Ebbie. But here, it is not unusual for a standing woman of pretty well any age to be offered a seat by any well-mannered gentleman ~~ even now, in my 80s, I have to resist the natural impulse to stand for a woman in her 20s-30s, reflecting that she is nowadays probably better able to stand than I am. Whereas, for any man to be offered one by a younger person, he would generally need to look pretty decrepit ~~ hence my horror!...
