I think cleanliness and avoiding sick people are the best defense for avoiding the flu. Hmm, sounds familiar. I wonder what % of people get the flu vaccine each year. Less sick = less distribution of virus cells.
To be honest I dont even think its the cleanliness.. I'm not saying I am filthy but I think I wash my hands about 2 no more the 3 times a day when I'm working in my shop(about 6 hours a day) but I do get brake cleaner on my hands ALOT if you want to call that washing
