Today was a banner day at work. One co-worker called in sick, two others left early because they were starting to feel sick, my wife is getting sick and the school called telling me to pick up my son because he's now sick. Welcome to a change in temperature this time of year.

I rarely get sick and I don't attribute it to much of anything. I just say I have a strong immune system, but there's more to it than that. Here's what I do.

I tell myself I'm not getting sick.
Sounds easy enough, but you also have to believe it. Mind over matter and all that.

Watch your hands -- a lot!
Before you go to the bathroom, after you go to the bathroom, before you eat anything and, well, just because. Seriously, think how dirty your phone or keyboard are right now. Would you eat off of it? And you're just typing away all day, then reaching for that can of pop or sandwich or something? Yeah, keep that in mind. I'm not a germaphobe, but it doesn't mean I like germs.

I stay positive.
You know the phrase you are what you eat. If you eat nothing but garbage you'll feel like garbage. Same goes with attitude and outlook on life. If you keep your head high, I really think it does help.

Also, don't eat garbage.

That's really about it. Keep your hands clean, avoid sick people and you should be good. I mean, think about it. Sick people see doctors all the time and doctors never get sick.
