One year on from his diagnosis, Moody notes that his symptoms remain concentrated in his upper body, with his strength diminished in his hands and shoulders.

The Rugby World Cup winner also experiences rapid drops in energy. However, discussing his partner of over 20 years, Annie, Moody has emotionally disclosed that he'll have her unwavering support throughout the fight.

"She said she'd be there no matter what," Moody told the High Performance podcast about his wife, with whom he shares two sons, Dylan and Ethan. He then opened up about informing his children of his diagnosis.

Moody said: "As soon as we found out, I said to Annie, 'I'm going to tell the boys as soon as we get back.' We probably talked about it in the car.

"It's horrible telling your kids that, knowing that as a parent you've brought this disappointment and sadness. Telling your kids is hard. You don't ever want to feel like that. But as soon as you've told them, you can then move forward."

Despite fearing for the future, Moody admits he is at peace with his diagnosis and is keeping an admirably positive outlook. He said: "It doesn't mean you're going to die immediately.

"We can look into drugs, we can look into trials. Prior to that, you can't do anything because you don't know what's wrong. We just have a great time and are seeking to do that as often as possible. We will laugh, we will live, we will love. I choose to live a hopeful and positive life. I don't see the point in being any other way."
