I have no medical training, but I have always believed sleep is underrated.. this article makes sense to me.. especially relating to Cancer, which seems to be exploding the past 2 decades.. growing older population naturally has trouble sleeping, added to a seeming pervasive attitude that couples sleep with laziness.
from my perspective, sleep = repair.. healing. it should be embraced.
