when you get a cold or flu it's due to another person who you were around or something you touched that made you sick! Or do you think that when you get sick it's due to being out in the cold weather or maybe you got caught out in the rain or snow. Ya know how your mom would say put your hat or coat on cause you will get sick. Or don't go outside with wet hair after the shower. I remember when Jenna was little and it was a very windy day and my MIL was with me she was like hurry hurry get Jenna inside she will get sick from all this wind. lol.... I think when you get sick you get germs from something or someone you came in contact with. As far as the weather I don't know! What are your thoughts?
