My Neurologist got me hooked on this show. Seems the last time he upgraded my computer brain feed I wound up with an eidetic (photographic) memory for 3 days. The Sheldon character supposedly has the same thing. Well, let me tell you if you don't have a photographic memory count your blessings. I know why Sheldon doesn't drive. Imagine remembering every vehicle you pass forever! On the drive home I had to close my eyes(my husband drives) ! I drove my whole family crazy with a running commentary of what had been going on all day. I still remember exactly what went on during that drive home including what people on the street were wearing.
This,however might be why they are trying it on people with Alzheimers.
