I was diagnosed with cystic fibrosis when I was three years old and my parents were told that I wouldn't make it to the age of 16.
I started karate when I was 14. It was a lifestyle choice - I didn't want to let cystic fibrosis debilitate me.
I found that taking part in sports that I love could help add years to my life expectancy - I'm 22 now and I don't plan on letting cystic fibrosis beat me anytime soon.
Exercise can really help people with cystic fibrosis and I started a poster campaign with Fixers to encourage other people with the condition to get fit.
Affinity Sutton supported me with this Fix.
Me and my friends want young people to know that calories aren't the enemy!
