Actually, he's my father's brother. The nearest difibrillators to us are 5 and 6 miles away in different directions. After that l don't know where they are but, like LW they seem to be everywhere. The last first aid course l went on we used them on the dummy and they (the defibrillators) told us what to do. l've never used one in real life although have done CPR in the past.
