But why is it that if you imagine a baby who smells of milk, for example, you can't help smiling? Why is there such an agreement around the world about what is or isn't a foul smell? Who decided what smells bad? Is it impossible that somewhere in this world there are people who, if they sat next to a homeless fellow they'd get the urge to snuggle up to him, but if they sat next to a baby they'd get an urge to kill it?
