Whales, dolphins, and humans are the only mammals with salt-water secreting ducts at the corners of the eye. They say that humans evolved into whales and dolphins -- they spent so much time in warm, seasonable water that they went native, they evolved to fit it, they left the whole poisonous clusterfuck of human interaction for the embrace of the seas where a whole other show was going on, involving poetry, love, and brotherhood. That's what they say.
