The problem with the world today is all these stupid studies on this is dirty and that is dirty... germs are good for your body and good for your immune system... I dont know about everyone else but I rarely get sick... when I say rarely I mean maybe once in the past 5 yrs?? I dont wash my hands after handling my snakes and I kiss my dog... I can even vouch for a couple times where i had been talking to someone and my dog layed a good one on me and his tongue went in my mouth... I'm still here and I'm as healthy as ever... To me its those people who go out of their way to make sure everythings clean and theirs no dirt on anything that get sick the most... 5 second rule.... naw more like 5 minute rule... What doesnt kill you makes you stronger and builds up your immune system... If you want to be healthy and have a strong immune system you need to give your body practice killing off germs.
