What is the age limit to be called old?

Hazel McCallion, is a Canadian politician and businesswoman who served as the mayor of Mississauga, Ontario from 1978 until 2014.

McCallion was first elected in November 1978, and is the longest serving mayor in the city's history, having served for 36 years at the time of her retirement in 2014, at the age of 93. Early in her career, a psychic predicted that she would only last for one term of office. Instead, she was a successful candidate in 12 municipal elections, having been acclaimed twice and re-elected 10 other times. Her supporters gave her the nickname "Hurricane Hazel” because of her outspoken political style.

On her 90th birthday in 2011 McCallion was assessed by Dr. Barbara Clive, a geriatrician, who stated that "at 90 her gait is perfect, her speech is totally sharp and she has the drive to still run this city. She’s the poster child for seniors".

This year Mrs. McCallion was named special adviser of the University of Toronto in Mississauga for one year.
