What do you think you will be doing on a typical weekend when you are over 90 years of age? As you think about whether you will even reach there, you could pick up ideas of people who are already nonagenarians.
One such person is 94-year-old Queen Elizabeth II, who was pictured at the weekend enjoying a ride on a 14-year-old Fell pony named Balmoral Fern.
This was in Windsor Home Park, west of London.
The Queen is the Patron of the Fell Pony Society and is well known for her love of the breed, as well as owning and riding Fells throughout her life.
The Fell pony, according to information from Wikipedia, is a versatile, working breed of mountain and moorland pony originating in the north of England in Cumberland and Westmorland (Cumbria) and Northumberland.
It was originally bred on the fell farms of northwest England, and is used as a riding and driving pony.
Meanwhile, from an early age, Queen Elizabeth II also had a keen interest in horses.
Into her reign, this developed into one of her main leisure time activities, with a particular emphasis on the breeding of thoroughbreds for horse racing.
