Due to the currentH1N1 pandemic, it makes sense to get our immune systems working at peak performance if you are not eligible for the flu shot.
This also the cold and flu season and there is no shot for the common cold unless you count granddad's hot toddy!
With Cancer rates rising despite millions raised for research, it makes good sense to fight it before it begins rather than fighting for our life with an uncertain fate. There are many more diseases which our immune systems could stop in their tracks if it were tuned up to peak performance.
We, as a society take better care of our vehicles than we do our bodies!
