I rarely get sick, to be honest I can't remember the last time I went to the doctor. I do have some throat irritation, but that is normal from time to time. As far as getting a cold and staying home from work/school it doesn't happen. *knock on wood* I know people who are sick at least two times a week. Which I don't see what they are doing to feel so ill. I guess some people are just prone to sickness and health problems. Thankfully I take care of myself to avoid having a run in with a deadly flu or cold.
