It's easily enough done Mick and like you, I've had my fair share of 'near misses' and it's only afterwards that you realise how bloody stupid you'd just been. Difference that some people will learn from that experience and some never get the chance. Just goes to show how narrow the line can be between a jolly jape and catastrophe.
I wouldn't worry too much about your high horse Mick. we all know where you're coming from (I think)
