Yep,,,ain't it a beach.. I have had good results with hand sanitizer. They come in little spritzer bottles and are easy to use. I make an effort to never touch my eyes or face without very clean hands. I stay away from crowds ,,,especially children with runny noses. It has just become second nature to me now to wash my hands all the time and it has helped me avoid lots of common colds . Hope this helps you some too.
If we would read the secret history of our enemies,we would find in each mans life sorrow and suffering enough to disarm all hostility.
