::::Discourteous of me not to respond to your side note re a heavy cold, N. Seems to be you're having a rough trot lately, after the knee injury. Your long-distance running should pull you through, I hope. I have the same problem: bronchitis. Overheard my wife complaining of sleeplessness to her sister, caused by my somnolent coughing. I was sleeping but hacking away apparently. Slipped out at midnight, bought a pack of fags and smoked two, which resulted in her catching, finally, 50 winks. Not the sort of provisional fix doctors would advise, but it works (in the short term)! I was compelled to run long-distance by my public school,  after being forced to run on a Saturday as a punishment for setting off a fire-cracker in class, and unfortunately sprinted in 11th out of a field of 350 over 15 kms. It took a bit of willpower, but I managed, once they'd drafted me as a promising marathoner, to come last in successive competitions. So the freedom of Saturdays was won back, and I could restrict the pleasure of distance running to racing my dog in the pastoral and solitary backwoods around our home. Fuck authorities!
