How could it happen?

It’s boiling hot here. Putting on a suit for work is a torture. The simple act of putting up three shelves caused yours truly to break out in sweat. So how the blazes can I have ended up with a sort of summer flu? Aches and pains, snotty and coughy. I’m feeling pretty groggy. I just don’t understand how I can end up with a cold right in the middle a heat wave. Must be old age or something and I’m sure the smoking doesn’t help either. Must give up (How many times have I said this?).
