This just cracks me up
My grandma would say if you go outside barefoot you were going to catch a death of cold. Now, in my head I say, because you know colds come through people's feet.
Or when they go out of town and they say they caught a cold because of the different climates. She says everytime I travel, I catch a cold. I have told her before that she catches a cold (if it is even a cold probably allergies) it is because of a virus (your body hasn't had the viruses in that area) and they don't look for wet hair, barefoot people, or people who just came to town.
Being cold does bring down your immune system so I guess if a virus is hanging around on a door knob, grocery cart, and you are barefooted and cold, then look out
. Dont' even bring up sleeping with the a/c on. The only truth I have found in that one is that it can bother my asthma (not a virus) and it can bother people's sinuses. If you are a person that has bad sinuses and you know that once your sinuses are bothered, bacteria sets in and you get a virus then don't wash your hair, sleep under the a/c. , etc.
I admire the people that don't ramble.
