Quite frankly on looking around I rather think it may well be so,how things have changed in a multitude of ways since our parents were approaching their 70`s.......in fact people today bear no resemblance,whilst are altogether in better health,many still working,holidays and all manner of leisure is very much enjoyed.
With ample better foods, medicines and advances in all forms of surgery, health is better.
Technology has changed the face of the older folk too so that they are constantly updated,kept in touch with the worldly happenings every minute..... if they so desire.....life is a totally different "ball game" it would seem.
Do you as the OP think so and what are your reasons for asking.............and perhaps,thinking this??
