Paddyanne I think you have misunderstood the discussion. It has nothing to do with looking or acting old anytime soon or any time ata ll
It is everything about taking pride in appearance while rejecting the desperate search to look younger than you are, as if your chronological age was something to be ashamed of.
A woman of 70 can still have her natural hair colour, be tall and slim and in good health and have the money to dress well. A woman of 70 can be short and plump with white hair, have severe arthritis and dress (very well) from charity shops. Both look and are typical of their age, because there is no typical 70 year old, anymore than there is a typical 10, 20, 30, 40, 50, or 60 year old. At 10 my DGD was in 13 year old clothes. At the same age her brother is in 8 year old clothes.
It is the assumption that is made that all older people want to pretend they are younger than they are, because being old is something to ashamed of and the way older people themselves buy into this trope that makes me so cross.
