Here’s a nice joke from the BMJ:
For those of you who watch what you eat and drink, and worry about heart disease, here is the truth””according to a joke currently doing the rounds. The Japanese eat very little fat, while people in Mexico eat lots. Both groups suffer fewer heart attacks than the British or Americans. Africans drink very little red wine, while the Italians drink large volumes of the stuff””but both these groups too have fewer heart attacks. An epidemiological conclusion might be that you should eat and drink what you like: speaking English seems to be what kills you.
