This is the point, of course, at which a cleverer blogger would have made a large and complex equation taking all the factors into account, and all equalling tired. Number of formula that I should be putting here: 1
Number I will be putting here: 0

Because I would have done that: but cant, as I gave up maths as soon as I was legally able to.
Oh, why didnt I listen when they said algebra was going to come in useful one day?

Well, probably because in all those years, this is the first time it has. And it hasnt, even then.
Even now? Then? Now?
Now, then.

Also I wont be doing the complicated formula thing because I am tired.
You may be able to tell.
