As people age, they often hesitate and wonder, "Can I really do this at my age?"

Seeing this person will likely change your mind.

A woman wearing a flight suit has climbed onto the wing of an airplane.

She even shows the composure to wave and greet those around her.

A grandmother in the UK took on this unique challenge to celebrate her 99th birthday.

Secured tightly with safety equipment, she performed "wing walking," showcasing stunts atop the wing of a moving airplane.

By successfully completing this extreme sport at the age of 99, she even set a Guinness World Record.

She is a grandmother who truly demonstrates that age is just a number!

Her challenge reportedly also raised donations for a charity.
