Any time I can lie down on the ground in the sun, I feel great. Warm sun and fresh air. If it’s after I’ve just finished swimming in a body of natural water, that’s even better.

Imagine jumping into cold water, feeling the shock, swimming around for a bit, then feeling tired so you paddle over to a big slightly sloped red rock, and you lie there on your back. The rock is warm from the sun, and stays warm underneath you because it’s been absorbing heat all day.
