One of those jobs we get a lot of – 'male collapsed in street, facial injury'.
So we arrived to find him face down.
I rolled him over, he didn't have a pulse, he wasn't breathing.
We did what we do – we tried to restart the heart, to bring him back to life.
The details are unimportant. What is important is that on that day someone's husband died, someone's father, someone's son.
There was no warning, he just dropped dead.
One moment alive, the next moment gone.
He was only a little older than me.
If this job has taught me one thing, it's that our time on this planet is precious, and that time can end at any moment.
So live life to the full. Make yourself happy. Try to make those that you care for happy. Your life is the only thing that you truly own and you only get one – so don't sweat the small stuff.
