The smoking is so nasty that it drives me out of the bars, cafes, and restaurants in Europe. On the other hand, outside of Britain, they are far thinner than Americans. Why? They walk a lot, partly as a routine, partly because of ubiquitous public transportation, and they climb a lot of stairs to the trains and in their apartment buildings. They linger over their meals and so eat less, because they don't shovel it down before the feeling of fullness kicks in. They also do not yet eat enormous amounts of sugar and salt with everything. Americans are not adding sugar and salt that much; their food and drink are already processed with them. So, much better to eat a pastry a day and drink coffee with a spoonful of sugar than to drink a handful of cokes or frappucinos and eat potato chips and candy like Americans do. European countries average 3-16 percent obesity, versus 34 percent in America. And Americans walk only a little over half the number of steps per day (30-40 minutes less) than Aussies and Swiss. Lifestyle is a huge factor--the Amish walk three times as much as typical Americans.
