I atribute that to good sense and not being around alot of poeople or crowds. Having family or friends that or sick or think they are sick keep away from me. Drinkin Prbiotics and DanActive every day. Keepin my house free from dust. Keepin away from hospitals (since retired) where MRSA is at its highest. To be this healthy for almost a year this Dec, I must be doing someting right. Even in Feb when I had my back surgery. No MRSA!
