Even the French are worried these days about putting on weight.  Although obesity isn’t the problem here that it is in the States, the indicators are all moving in the wrong direction.  A new social marketing campaign seems to be everywhere, urging folks to make sure they get 30 minutes of exercise a day without even working up a sweat.  Three minutes here, ten minutes there, it all adds up.   Since sports aren’t really a French thing (except for maybe tennis and fencing), this campaign seems to me to be hitting the right note.  Whether anyone will change their behavior — well, that’s a different story altogether.
