I spend alot of time trying not to get sick! I haven't had a bad cold in years but I do remember having the worse colds and flu when I was a child. The older I get the better I feel. Don't have any of the kids around to pass on their ills from school. Do you take vitamins? Try taking some Echinacea a couple of weeks at a time for a few months to build up you immunity. But wait until you're not sick any more to start. At the onset of anything I double down on it for a few days and it seems to knock whatever is trying to get me. I love the more natural remedies.
