“When my wife was pregnant, I remember going to the scans and these doctors would…” — Alex Brooker

All my conversations I've ever really had about being a disabled man, I've had on telly. It's a really strange thing, and it makes you feel quite exposed.

I just wanted to do the documentary to shine a light on disability in perhaps a different way than I have done on television so far. But in a selfish way, it was about learning for myself. Getting to a stage where I felt able to talk about these feelings I've had over the years.

When I did 'Sink or Swim,' there was a moment in Lake Windermere where I struggled, and I felt for the first time in as many years as I can remember, that my disability was beating me.

When I applied for Channel 4 I was a sports journalist. I saw it as another sports journalism job, if I'm honest.
