You're ringing a bell for me with this observation!
Every May since 1968 I always seem to wake up on the terraces of a football ground somewhere, mainly Maine Road and The Etihad but also far flung places like Newcastle, having gone there and immediately fallen asleep. The medics have been at a loss to explain it.. but from what you suggest, maybe it's some form of 'football-induced narcolepsy'?
I mean, it's been going on for donkey's years.. I drop off for hours as soon as my team comes onto the pitch; even spoiled my afternoon at the end of last season when I was looking forward to see the return of Philipe Coutinho to the Premiership.
I must get another appointment with the quack, see if this might mean something for the diagnosis?
Oh and by the way, while I'm on here, can any of you tell me what's the obsession among Blues with the number '93.20' all about? Beats me why I keep seeing it everywhere..
