You know what we should do?

Get out of it for a while. Get into the countryside. Rejuvenate.

Rejuvenate! I'm in a park and I'm practically dead. What good's the
countryside?

.........it WAS cold, but once I'd got up against a radiator and covered myself in deep heat I started to recover.
It was a great weekend and I've come home with a car full of samples to test. The first photo is Grimley Andesite - well a stream full of it - and the second is a disused diorite quarry. Every view I look at now is stripped to the bare bones of its bedrock geology. When I close my eyes the stars I see are quartz phenocrysts. Maybe I've been out in the field too long........
