Building your immune system  

My boyfriend never cleans anything, well almost never. If pressed he will wash a load of laundry or wash the dishes. Even he admits that he has only washed two loads of laundry in the last year since I do it. I am always finding sticky, dusty, musty, and just disgusting messes around the house, not to mention the way that he leaves a bathroom and the filth on doornobs, walls, and countertops. I go behind him and clean it up mind you. Though I am not the absolute cleanest person or best housekeeper in the world. Whenever I point out one of his funky habits or messes he always replies good I am building my immune system! This infuriates me! Germs and sticky unattended messes and handprints do NOT repeat NOT build the immune system. If anything leaving germs and bacteria lying around the house has got to break down the immune system not build it up I would assume. Yes some bacteria and germs in your enviroment do help your immune system but I fail to see how a pepsi cola spilled a month ago and all of the stuff that has collected in that nasty syrupy sample do anything but collect harmful germs and bugs, which bring in more germs into your enviroment!

Do you agree with me or him. Does being a slob and leaving unneccessary germs and bacteria in your home build your immune system or is it just a petri dish of infectious agents ammassed and awaiting an avenue of ingress into your body that the immune system will have to fight off?
