#1: We All Float On
I don’t know if I just spent too much time watching action movies when I was younger, but I used to be convinced that at some point, I was going to find myself stranded in the middle of the ocean and need to be able to tread water for a long time until I was rescued. So I practiced it a lot and actually could tread water for quite a while at one point.

Turns out I could have saved myself all of the efforts! Just by holding your arms and your back in the right way, you can float pretty effortlessly. This is a great thing to know how to do because if you ever do find yourself in this situation, you could find yourself needing to be out in the water for a long time. If you could do it without actively treading water, you can save a lot of energy and last a lot longer.
