Spending time underwater
I can spend a pretty long time underwater without an oxygen tank and snorkel mask. It’s not like I take a big deep breath when I go underwater. I basically drop down under the surface and I hang out. I look around at the fish. I look up at the Sun reflecting through the water. I read a plastic book that I brought with me. The time flies by.
Once I spent a week under water. Some of the time I did the things I mentioned. Other times I slept. I ate plankton. It’s full of nutrients. And when I got thirsty I swallowed some of the surrounding water. When I finally came back out into the air, my skin was pruned. It took a few days for it to flatten out again.
