I once thought about how the world would be different if we were like rodents and essentially lacked bladder and sphincter control, if we'd have to all wear diapers all the time (think of the landfill waste so probably we'd have figured out something else but what) and what ballgames would be like. Probably holes in the seats. Because how else could we have a functioning society? We'd actually probably be a lot better at sewage control because otherwise it'd always be everywhere.
