Real Tennis is Old

Actually, the real tennis isn't even tennis. It's something called Jeu de Paume, of which "lawn tennis" is a simpler descendent. There still exist some Jeu de Paume courts in Europe. As I am not athletic, I got really tired just reading about this old sport, and so am giving it to you because I know you are extremely athletic and will therefore find this absolutely incredible! Then you can tell me the good parts later when I wake up from my nap.
