The PossibilitiesI'd explore all the little caves at my favorite swimming spot, chase fish and nap underwater. I'd tie myself to a large rock and sit at the bottom and watch the sun filter through the alders and redwood, and try to make out clouds past the rippling water.
I would watch the bubbles surface from the people who swing into the water.
I'd take my wetsuit to Monterey bay and explore the bay in just that. :)
Heck, I'd buy me some fins so I could explore everywhere faster and explore more places. lol. I'd invest in a mask if I could breathe underwater.
I feel like a little kid again...dreaming about being able to breathe underwater. :)
