I don't like french people in general, arrogant, pussy-ish and very american-culture wannabes, I also hate Paris, this city you can't drive for shit, you can't have a drink without paying over 10 euros at a pub, there's nothing good in this city!
I don't think french are obsessed with weight, also french isn't even currently in the top 20 of the country with the most weight problems ( USA is like the 2 nd country with most weight problems, first country being mexico ) if I remember correctly.
Where do you come from?
At the moment I don't have any money for a bike unfortunately, but I wish I had !
