1 Hitherto unsuspected tattoos are on display, often requiring wholesale mental readjustment in social perceptions. It is frequently these, rather than the heat, that are making you dizzy.
2 You are unable to face drinking tea or coffee and spend much of your day trying to work out how to caffeinate the water cooler.
3 If you live in the city, the air is visible and has to be cut into manageable chunks before it can be inhaled. If you live in the country, your smug air is visible and you are in danger of being cut into manageable chunks by desperate urban refugees.
4 You come to believe that deodorant is GodÃ¢â‚¬â„¢s own stickful of petrochemical derivatives.
5 The cat is scratching the words Ã¢â‚¬Å“Shave me, shave meÃ¢â‚¬ï¿½ on every available surface. The dog is writing letters of complaint to the design committee that dictated that panting rather than, say, unzippable pelts should be the main method of canine temperature regulation.
6 Sex seems like the worst idea anyone has ever had, ever.
7 A visit to the shops makes you deeply aware of how very far we still are as a nation from embracing the pedicure as a standard component of personal grooming.

12 Foreigners walk around in thick coats and long trousers insisting that if this happened at home they would still be huddling round log fires.
13 You suddenly have veins like jungle vines and, if you listen very closely, can hear blood vessels popping under the most minimal physical exertion.
14 You sleep naked and spreadeagled, like a pornographic starfish.
15 You elbow old ladies in the face to get the last electric fan in Comet.
