You can and will die from extremes in either direction. > In heat, you can survive without air conditioning. No, you cannot, beyond a certain point. You must have a way of removing body heat, and that requires active cooling. The body's own evaporative cooling is only reliable up to a certain (modest) threshold of heat; thereafter, external cooling is mandatory, or hyperthermia and death will ensue. > Drink lots, have a fan, dress properly. No problem. See above. In high temperature and humidity, a fan and drinks will not suffice, as they will not be able to remove body heat quickly enough through perspiration to prevent hyperthermia. Using a fan also raises temperature and humidity. > If you turn off your air conditioning and follow the above, > you will have gotten used to it within days.

However, with the right clothing, you can tolerate any cold air temperature that you are ever likely to encounter on the Earth's surface. > And you still need to drink and eat properly.

You just need warm clothing, be it a sleeping bag or something else. > It is easier to learn to survive in heat than in cold. No, it's just the opposite. You can survive cold with protective clothing alone. In heat, you must have active cooling. > At 40C, you are only 20 degrees from optimal temperature.

But at 40 C, heat must be actively removed from your body, whereas at -20 C, you need do nothing more than conserve a portion of the heat your body produces. -- Transpose mxsmanic and gmail to reach me by e-mail.

Apparently not Europe, or you'd > be visiting rte more! Spent a month in Europe around May but was kind of on autopilot. Two weeks in Holland, then went down to Sevilla for Feria season. Couldn't get a flight to Sevilla (everything full), so I looked on the map and the closest place with cheap flights turned out to be Faro, Portugal, on Transavia. It only looked to be a couple hours away from Sevilla on the map, so I figured there'd probably be hourly trains or something. Boy was that guess wrong. I got there and there wasn't even daily scheduled bus service - I arrived on Saturday and the next bus was Monday. No train at all (except via Lisbon!). Finally on Sunday someone tipped me off to a secret bus, the existence of which had been denied by everyone else, that made the trip in only about 4 hours. Feria was quite a sight though. At the same time, the cultural monotony of Sevilla is unsettling. A giant city, with something like 6 restaurants (not including fast food) that aren't Spanish/French/Italian. Every one of those 6 was full of foreigners and (by their accents) madrilenos, not a sevillano in sight. It's very beautiful, but I can't deal with Spain for long. > Me, I got married and moved to Italy, and am loving every baking > moment of summer! Congratulations. Does this mean you'll be settling down in one place? miguel -- Photos from 40 countries on 5 continents: http://travel.u.nu Latest photos: Malaysia; Thailand; Singapore; Spain; Morocco Airports of the world: http://airport.u.nu
