One of the most impressive things about Hong Kong is the absolutely incredible bladder control you will find on display throughout the city. Forget about the Chinese acrobatic acts featuring intense young Buddhists smashing their forearms through concrete cinderblocks.

Our table was littered with empty bottles of mango and raspberry juice purchased at the local store. "But we also don't drink so much juice, and that makes a difference too."
