Mind and Weather....

Have you ever noticed that our mood swings with the change of the weather.... I know this sounds good and also ridiculous. But I often think have had this experience, if the days weather is dull, I tend to be dull and I dont feel like doing anything.... If it is rainy, I am exuberant......seems funny eh! The most funny thing is that even if I am sitting in a AC room, totally un-connected with the outside environ, I can sense the change in my mood with the weather..!
