My next door neighbour has probably learned that lesson now. About a week & a half ago he rang me and said, mate I've had a fall and I can't get up. So I went over and there he was on the floor, leaning on a chair and puffing like a steam engine. With great difficulty - he's very overweight - with him pushing and me pulling, we got him up into a chair. I said have you got a BP machine and he has and we check his BP. Extremely high. I said we should call you an ambulance. No, he wasn't having that, he'd go & see his doctor. Well he did the next day and the doctor said he'd call an ambulance for him and gave him a letter for the hospital. But again he says he had things to organise at home. So it might h ave been the next day I get a call. His house is on a steep rise and he had walked down towards the gate to meet a cab and he'd fallen over again and couldn't get up. So I went over but I couldn't lift him so this time he called the ambulance and I think they probably just got there on time. He's been in the cardiac ward for about a week and had every test known to man. He has to have a valve replacement and a bypass and some fatty tissue cut off. Open heart surgery.
