D-day.

Attentive NB readers may remember from last year what this equation...



...calculates.

It calculates today!

Ergo, today's issue of the NB will be devoted entirely to something we know lots about. No, it's not how to look good even on the bleakest of days, silly! It's depression!

So, happy most depressing day of the year day! Hang in there. It doesn't get worse than this.
