As the Beijing Olympics comes closer with every passing day, the Games' influence on our lives is also increasing: commands to stop smoking and a ban on free plastic bags; when taking planes you can't bring shampoo, or lighters; when sitting in economy rows you can only bring one piece of carry-on luggage....I hear that these rules will soon apply to subways, too: on the trains, you can't even bring a fruit knife...there will probably be more and more rules.
