On Monday morning I was up early and posted the following message to Usenet:
'Graham and I drank some brandy last night. Not a terrible amount, but we were slightly light headed. I went to sleep fairly quickly, but - as usual - woke up to obey a call of nature at 4.30 and couldn't get back to sleep. This is a fairly recent phenomenon, and only seems to happen after I have imbibed. The fact that there was a large bulldog snoring in my ear undoubtedly didn't help! This is why I am up and bloggifying so early!'
One of the replies I got was from Lawrie Williams:
"I thought most men wake up at least once and often 2 or 3 times at night for a pee. It refreshes the system to have to move around and I suspect it is the result of selective pressure - no joke intended - in that the head of the family gets to detect enemies and predators and infidelities. For a typical clan grouping of 20 people it would mean someone was always up and about during the wee small hours".
Is this true? Or a modern legend arising from the physiological changes in ageing men? And why can I never get back to sleep when I have had a drink or two?
