The Swelt

Sweet Louise, it’s hot! Here’s a list of things you can do to cool down:
1. Live underground (this is how worms keep cool)
2. Live in the past (cf. old Christmas card images, the Thames freezing, a world before global warming)
3. Eat less coal (this is a fossil fuel)
4. Get as far away from the Earth’s core as you can
5. Think of an Inuit in ice
6. Stop complaining (this can cause your blood to boil)
Any more hints?

Lick your finger then wet your earlobe. The peculiar sensation of trying to work out if you enjoyed that or not takes your mind of the heat.
Replace the sun with an iceberg. And take off all your clothes.
