The following video floored me.
Dr. Jill Bolte Taylor is a Harvard trained Neuroanatomist or in plain English: a big wig scientist who studies brains.
JBT had a stroke in 1996. The video is of her speech about the event, her recovery and most importantly what she learned about her essence by experiencing a brain trauma from the inside out. It is a fascinating presentation on every level.
