Wow, I’m really dense!

Yeah, we already KNOW I can be dense in the mental arena, LOL.

But what I’m talking about is my mass/volume ratio.

Because tonight I was swimming my laps after water aerobics and wondered why, sometimes in the shallow end, when I was slow on my flip turn, why I would sometimes find myself sitting on my butt on the bottom of the pool after exhaling.

So once I finished I did a little experiment. I laid on the surface and let out my air. Woosh. I landed on the bottom. I held my breath down there for a little bit to see if I’d come back up. Nope. So I stood up.

And then I told the lifeguard I was going to try this in the deep end, just to find out if I really was sinking. And I went down there over by the ladder and did the same thing. And I sank like a stone. It was so fast I actually got a little scared and started swimming back up before I hit the bottom (12 ft). My ears were even feeling the pressure.

Dang. Now I think I understand why some people are afraid of water, especially deep water. It would be kind of scary to find myself at the bottom down there and what if I didn’t have the energy to pull myself back up to the top and wanted to breathe? Yikes.

Last time I was that deep (about 18 months ago) I swam down to retrieve a piece of the underwater vacuum for the lifeguard. I was so buoyant that they had to put down a pole so I could pull myself down the last few feet using my arms, because I just couldn’t swim against my own tendency to bob back up.

This time I think if I went down there again, I’d ask for a pole so I could pull myself UP, if necessary! Heck, if I could hold my breath long enough, I could probably walk around down there.

Bizarre. This whole physical metamorphosis is just bizarre. In some ways it’s almost as surreal as waking up one morning shaped as a cockroach. LOL
