Hello and welcome to the first episode of Life-Changing,

a series where I talk to people who have experienced something utterly extraordinary,

a turning point in their lives.

And we're going to start with Grace Spence Green,

who in the October of 2018,

were seriously injured in an event that was as dramatic as it was unpredictable. Let's meet her.

terrible day in August when you junior doctors actually start being doctor doctors? Is that

Finally, so I'm very excited and apprehensive for that moment.

There's a rather bleak, some would say, tasteless humour surrounding that, though, isn't there in hospitals?
