The more we uncover, the more we realise how delicate and fragile these processes can be.

In 2006 Steve Steere was in an accident that would change his life for ever.

Steve was always a very active person.

He had done two sponsored rides, one to Mexico and one to Ecuador, which he thoroughly enjoyed and he was training for the third ride, which was to go to Peru,

when he had an accident, he was found unconscious and he was taken to hospital, where they diagnosed him with a fractured shoulder.

Initially, Steve's injuries seemed relatively minor.

But early the next morning things took a turn for the worse and he had a massive stroke.

This left him with severe brain damage.

He was told he'd never talk properly again.

I remember watching a programme probably six months before Steve had his accident, which showed a lady caring for her disabled husband and I remember feeling, "Gosh, if that happened to me, I don't think I'd be able to do that."
