IgA!

So, um, a long time ago, an experiment was done when two groups of people were exposed to different conditions. One group was exposed to happy HAPPY conditions, such as watching really really funny movies until their eyes teared up. The second group was exposed to sad conditions, watching movies that make you cry etc.

Well, IgA is an antibody that is secreted in general in all mucosal membranes, including tears. When scientists tested levels of IgA in tears of these two groups, they found that IgA levels were MUCH higher in the happier conditioned group than in the sad group. This whole experiment was designed to test the relationship between the immune system and the nervous system. So it showed that IgA immunoglobulin levels directly correspond to how happy a person is!!!! :D *EE*

I don' t know what you think, but I think I'm QUITE the happy person! Thanks SO MUCH IgA!

So if you're EVER feeling sad...pray...to IgA. ;)
