Re: My cold won't leave me alone!
I don't think so, but hygiene is important. One thing is washing hands. Do you wash them often enough? If you don't wash your hands and go on touching your mouth, nose, eyes, you'll catch everything that goes around. Personally I have a habit washing my hands every time I return home from outside (from the town/shops/etc where there are many people), or start cooking, eating, drinking, and so on. The regular hygiene and then some. I usually don't catch anything, not a cold or a flu, but this year has been bad, due to other things... I have asthma by the way, this is why I'm trying to avoid colds as much as I can. If I catch a cold the cough stays with me for 2 months at least!
Hope this helps.
