Is that a worm?

So I'm swimming along and I note something in the bottom of the pool. Lap after lap, I see it as it progresses along the bottom of my lane in the pool. At first I think perhaps it is a stick, no it's not a stick. Then I conclude it is a worm riding the current created by the swimmers 6 feet above. Is it possible the current would cause the dead worm to reverse direction in a slow controlled manner. Yes, let me change lanes because for whatever reason the worm, which I now conclude is alive, is really creeping me out.

3 x 1000, then a 1200 today for a total of 2.6 miles. Why, I don't know. It hurts some, there are moments of controlled drowning, but eventually I find a peaceful place that is actually relaxing.

Tomorrow, the bike and hills await.
