It has something to do with the weather. Late July / early August is when summer gives way to typhoons, giving us weird temperature changes and swings in humidity and dust. It makes someone with allergic rhinitis and a sensitive respiratory system automatically sick.
It also coincides with, or is near enough, my birthday to serve as a reminder of mortality. Nothing better to suggest a fragile biology than a raging sore throat, fits of coughing, and a weakened constitution.
But then I get better after a couple of days and I binge drink. See you on Saturday.
