Parkour. Developed in France Parkour is derived from gymnastics and other martial arts. Parkour focuses on self defense through tactical retreat. Needless to say it takes a lot of guff for it. However the art continues to grow because it is fun and looks awesome. As a martial art I must give it some credit. Tactical retreat is sometimes a very good option.
MUST VISIT: The Abbey Bookshop, Paris, France "This mellow, Canadian-owned bookshop is known for its free tea and coffee (sweetened with maple syrup) sipped over new and secondhand books, fiction and non-fiction." -Lonely Planet
