I was just kidding, I know how serious it can be. There was an article not too long ago that was relating migraines to a heart disorder. More research was required, but they ran into the discovery through medical research in another area. Wish I could find that link...
I used to have migraines a lot before I got me wisdom teeth pulled. Now I only get them from certain fragrances.
I'll see if I can find a link for the migraine thing, so your not having an anxiety attack about your heart
