I never been sick before. Not since I was six years old.
It's all these people crammed in so close together half in buildings with windows that won't even open. No one's got no room to breathe and there's nothing in the air anyway but what people put there. Leave more room for your trees or plant yourself down in the muddle of a bunch of them instead of all these skyscrapers and you won't get caught with all this unnatural sickness.
