Some, recent study concluded that single people die quicker than people who live with others in the same household. For all intents and purposes I've been a single person for most of my adult life. Of late I've been itchin' to get a dog or two. I realize that human beings weren't designed to live alone. And by alone I mean in a household with no one else. I suspect that's why there are soooo many "crazy cat ladies." Nobody wants to be alone. Nobody. Even if your only interaction with "others" is with others of the four-legged variety, at least you're not interacting with only yourself! As for me, I can't see myself interacting with a half dozen or more four-legged creatures only. And mainly because I just wouldn't be able to tolerate the clean-up and SMELL!
