Does typing fast warm up cold digits?

Now we're back on the relative thing so bear that in mind.

It's cold on Dartmoor. Certainly below freezing, possibly a few degrees below. Yesterday it snowed and last night we had further wintry stuff, the combination freezing into an icy mass on the roads and pavements. We live in a subsidiary valley that slopes down towards the Walkham and, as a consequence, all roads in and out are on an incline - down to get in, up to get out. So getting to the shops - there's none in the village - is difficult, sometimes impossible.

Fortunately, we've got enough tins in; lunch is soup accompanied by bread filched from a friend. Tonight we should have the right ingredients for a roast and if we think about it a tiny bit, we've probably got enough stuff around the kitchen to last for a week or more. Not that it'll come to that, but when your boiler packs up and you've got no heating you start thinking in extremes.

As I said at the top of the post, this is a relative thing; we've got a house, we've got an electric heater, we've got plenty of clothes and we're only talking about a couple of degrees below freezing

To answer the question, no, typing fast does not warm up digits.

It just makes your paragraphs smaller.
