Single Men and their Health

I thought it was really interesting how single men are not as healthy as single women and it's actually interesting cause I can see why. I am in a relationship and live with 2 other guys who are both single. Our house is an absolute mess all the time because they don't feel they have any reason to clean up because the only people they have over are other guys. The only time they clean the house is whenever they think a girl might come over or if we have a party. I try my best to clean up every once in a while for my girlfriend, but theres only so much I can do when the trash is constantly piling up on the living room coffee table. I have noticed too that we have all been getting a lot sicker this past school year probably because of our living conditions. Trash can go a week or two without ever being taken out, milk will stay left on the counter until it goes rancid and other disgusting things like that. And of course anytime I bring it up they really don't care because they have nobody to clean up for. I think it would be really interesting to see what would happen to our living conditions if they both got into a relationship, or at least one of them so I could have someone take my side when I say our house needs to get cleaned up before we get an infestation.
