Air conditioning is what seperates first from second, third and fourth ( wherever they are ) world countries. In hot countries air conditioning experts have enabled a way of life never believed possible before, allowing commerce to continue during the day. In somewhat colder countrires ( like the UK for instance ) it is merely a way for those people who wear jumpers all year round to inflict their personal grievances on the entire staff. Those from colder countries who visit hot countries with air conditioning will have experiened the "Japanense Airport Effect" where you leave a chilled indoor space and greet the hot and humid outdoors by suddenly bathing in your own persperation.

Air conditioning is the best way for an entire building to share the fun of air-borne diseases, from flu to legionaires disease, what one has so all will share.

The most puzzling aspect of air conditioning is why do so many busy UK pubs and clubs either don't have it or don't use it. Instead of sweating profusly and breathing in other people's first and second-hand smoke we could be in cool fresh places, live longer and spend more money in exactly this kind of establishment.
