Fat Floats

As a kid, I was all skin & bones. When I was first introduced to a pool, I promptly sank like a stone. (BTW, quick way to learn how to swim).

In my twenties, a tad more filled out, I went for my Scuba certification. During the pool-length underwater swim, I expended as much effort trying to stay underwater as I did going forward. The instructor gave me extra credit for effort.

Now, in my robust maturity, I float like a bloated whale. You couldn't sink me if you tried. If floating on water was an Olympic sport, I would nail it. Birds have tried to nest on what I presume they saw as an island. 

Scuba?  Just a few more weights, please.
