HARRY Crowther may only be 11 but he’s experienced so much in his life already because of a rare genetic condition.

The Mirfield schoolboy has Atypical progeria syndrome which means he is ageing five times faster than his friends.

He was diagnosed in America and is the only person in the world to suffer with the condition.

Only recently Harry was diagnosed with arthritis and needs to take painkillers four times a day.

It has led to people being rude to him, but the schoolboy shows what an inspiration he is by rising above it.

He is refusing to let this life-limiting condition stop him from enjoying every moment he can.

And this weekend he’ll be rewarded for his positive outlook by meeting his hero Bear Grylls – a TV explorer and chief scout – after being invited to the St George’s Day parade at Windsor Castle.

It’s clear Harry gets his determination from his parents who are doing everything they can for their son.
