Am I down voted because people think I am just lying for fun, or because the idea that eating right and avoiding tight places packed with people keeping you from getting sick is upsetting?
A message reminding people that you can improve the resistance to basic colds/flu for a school teacher, tested on several school teachers, should be motivating for someone tired of being sick.
You asked why you're getting downvoted. I'm doing you the service of explaining it's because your comment looks spammy and annoying. Take the feedback...
