I find being a hermit is a good way to avoid the germs. Eating plenty of fruit is easy in the summer but I find cake, pies , sausages , eggs and bacon more appetising when it's cold. I've made a conscious effort to keep eating fruit this year and except for one heavy cold (caught from a guy I was working with for a week ) I seem to have avoided the regular couple of bouts of cold or flu I've usually had since I was a kid.
Ha, there's tempting fate eh.

Rust never sleeps !
