How old is 'elderly'?

from w
I was surprised to read in the Fiji Sun today that the journalist considered a 52 year old as 'elderly'. Of course it depends upon the point of view. When I was 20, I thought 30 was really old. But these days I do think that '52' ought to be in the prime of life! Meanwhile my good wishes for the recovery of the woman injured in another bus accident, this time near Labasa.

An elderly woman was admitted at the Labasa Hospital after a bus and a sugar cane locomotive collided at Wailevu Point in Labasa during the weekend.
The impact of the accident also left some passengers injured.

Northern Deputy Police Commander, Superintendent Bola Tamanisau, said there were more than 20 passengers in the bus."The bus was returning from Labasa Town to Wailevu in the afternoon about 5:30pm," said SP Mr Tamanisau.

The elderly Fijian woman, believed to be 52, was rushed to the Labasa Hospital after the crash. She is still admitted in the Labasa Hospital.
