“And new physical problems are arising almost daily. I'm getting problems from a painful trapped nerve in my shoulder, where my rucksack strap has been pinching it, and I can't straighten my arm above shoulder level - soon I will be limping like Richard III. By now my back is covered with eczema, the result of a perpetually sodden shirt and rucksack pressed against it day after day in this heat. In one place my pack has rubbed a painful hole in my skin through the eczema; carrying my rucksack was unpleasant before, but now it is purgatory. This eczema must be partly due to eating bad food for so long - I never had this problem at home. I'm expecting my teeth and hair to start falling out before long, and I've got more or less a permanent acid indigestion from eating so much junk. Week after week I've lived on lukewarm Coca-Cola, stale buns and doughnuts, slurps, green bananas, powdered milk and far too many cigarettes. With all the rubbishy food and sugar soft drinks I've been consuming, I'll see the east coast through a hypoglycaemic haze.”
