I'm an Aussie living in Scotland and find the warnings of "heatwave" conditions hilarious. When you've lived and worked outdoors in places where the temperature hovers around 38C in the shade (and does go higher), then edging over 30 is nothing to worry about. And none of my cars or houses had air-con, nor did those of most of the elderly people I knew. My OH feels the same. She's a Scot, but has lived in Egypt and knows what a real heatwave is like. Mind you, there's a similar amount of hysteria in winter when temperatures dip a little below freezing. People elsewhere in the world cope with temperatures well over 30C and well below -5C, but in the UK it's "shock, horror, we're about to die" time.
