Last time I cleaned insides and old bloke had a heart attack and was unconscious and not breathing. I had to give him compressions 15/1 I was taught, now they say it's 30/1. Brought him back round and someone had phoned the ambulance. He was the most thankful person, he was a really nice old boy, had to try, I was lucky as it had only just happened. Thank goodness for first aid training drummed into me every year. I never cleaned insides anymore after that.
