You know,having read that,I am certain I knew two guys who had a sleeping disorder. I would marvel at their ability to fall asleep anywhere, anytime instantly. Just thought it was the way they where,but now I wonder. In fact one of them was Joe perfect lifestyle,never smoked or drank,ate all the right foods,considered running up and down a 4000 hill a light workout.
But he always had a problem with high BP and it always puzzled me.
