Well I'm back from a killer workout at the pool. It does wonders for everything, including needing less sleep, getting stuff done more quickly and feeling grateful for what we have. It's so glorious, the water and sun with my kids.
It's horribly expensive to swim indoors in the winter around here, so I always end up gaining weight during Christmas, even if I fast for Advent. I have found homeschooling to be sort of fattening, because it's so homey, cooking, baking, sitting around due to learning styles.
I love the water because it's low impact and high resistance, but mostly because it elevates my spirits and I get twice as much done. No wonder people love to live on the sunny coastlines!
