I can't drink beer in the heat at all. I used to be able to when I was younger. Then I could do it if I drank an equal measure of water. Then it had to be at least twice the volume of water as beer. Now I can't do it at all. It means my weight goes down in the summer (which it needs to anyway!)
Thanks for all the tips on coping with heat. We get the humid type here in Köln. Once it has been much over 25°C for a couple of days, the moist air hangs in the Rhine Valley.
Kat has an interesting point about the high ground. That is what I found when I started going to Austria about twenty years ago. I just was not used to taking the sun at that angle. I also was not used to having it in my eyes like that. I have never been a sunglasses person (haven't got a cool enough image) but I really did struggle with the sheer brilliance at times.
On one hot afternoon at Linz Festival, I actually blacked out during a show. That sudden black, squeezing feeling in the head and then the sudden return. I was still on my feet, twelve kilos of drum on my back, guitar, harmonica and a balloon in my hand. One man banding in 35°C heat is not a good idea anyway, so blowing up a modelling balloon for a kid as well was probably not the best idea I had that day. I must have looked really stupid, because although I had only been gone for a second or two, it felt as though I had been sleeping heavily for hours. So I am staring with blank incomprehension at the hundred people standing around me - a crowd which it had taken half an hour to build up - thinking, "Why are all these folks looking at me?" When I realised what had happened, I blurted it out and asked for a drink. They thought it was another gag in the show! Eventually someone brought me something and I finished the show, which was a good one. I didn't do any more balloons though!
