I also have what one might call sea legs. I can quickly adapt, whether it's a thirteen foot river skiff or a mammoth cruise liner. The feeling of walking not quite being steady excites me. Except for when it's drunken walking, then I just feel dizzy. It's quite funny to watch ten people zig-zag and stumble in unison when a cruise boat lurches suddenly, by the way. Also weird is how it takes one night to become in sync with the wave rocking, yet spend weeks afterwards feeling like someone replaced my mattress with a waterbed. Hm.

The vastness of the ocean might be scary to some. I find it relaxing and humbling at the same time. Perhaps it's because all four of my DNA strands were sea-faring people. Brave explorers who used only the sun and the stars to guide them. Cheers, ancestors.
