Part of the show Alzheimer\'s
Stuart St.John asked:
I'm wondering about the fact that I and to of my sons are consistently able to wake up quickly, in a happy demeanor, whereas my wife and other son (a) have trouble waking up - no matter how much sleep they've had, and (b) have a somewhat less cheerful disposition. Could this be genetically based?
We'll have the answer for you on the next Naked Scientists Show. Until then, what do you think?
