Waking up

"The 'natural alarm clock' which enables some people to wake up more or less when they want to is caused by a burst of the stress hormone adrenocorticotropin. Researchers say this reflects an unconscious anticipation of the stress of waking up."

And all this time I thought I was just lucky.  The jokes on me!
