Have you had the horrid bug that’s going round yet? I’ve got it now and I do hope you get it too. But before I explain why let me describe the unpleasant symptoms.

These include: frequent headaches; burning lungs; watery mucus that makes you feel like you are drowning, later replaced by thick phlegm which makes you feel like you’re being suffocated; a raw, ravaged throat akin to swallowing ground tiger whiskers; a cough so tickly your sleep is like the ‘Albanian’ torture sequence in The Ipcress File; general dyspepsia, torpor, achiness and malaise; irrational, impotent rage over absolutely everything.
