I've had a cold most of the week. Had I not been in the Cone of Infection of a group of escapees from a TB hospital last Saturday in Equus, I'd have blamed it on the equinox to annoy people.

Hmm... Equus, equinox...

To be on the safe side I shall be avoiding any and all equations for the next few days, and resolve not to watch any episodes of 80s E-waa-woo-waa vehicle The Equaliser. Equilateral triangles are right out.
