Drying out

I went for a swim with my daughter today. I did 16 lengths of the 25 metre pool, she did 60! Still, that was a 60% increase on my previous effort. Next time I go, I shall aim for at least 20. Happily, the pool was not busy and I had the slow lane mostly to myself. The goggles are indispensable. I used to have prescription goggles but they were far from watertight and it's not as though I need perfect sight swimming up and down.
