That's nice. 
Fancy a dip Snoops? The water's lovely. 
Can't ~ Implanted defibrillator means I'm not allowed ~ even if I could swim, which I can't ... but thanks for the offer.
Wots one of them then?
Sounds complicated!

Snoops sweetie lie down, let me pat your head, do you feel alright?
I think typing may be stretching things a little, may be best to take it easy. 
All I do is take it easy.
I've had the damn thing in my chest for 10 years now so no need to lie down just at the moment.
Yes it has "gone off" in that time and yes it hurts like hell when it does but it is better than the alternative (I think).
And to answer the next question yes it has to have a new battery every few years and yes they have to open my chest (local anaesthetic), take out the machine and replace it as it is a sealed unit. It is about the size of a pack of twenty cigs and weighs about 4 ozs. Much bigger than a pacemaker which is about the size of the old half crown.
