Just a short post today.
A tale I first learned from Spark has bobbed in and out of my mind a lot recently. I want to tell the tale because it perfectly illustrates the importance of exercise in our lives.
It’s a story of a tiny, sea-dwelling animal called sea squirt. Sea squirt happily putters around shallow waters with the help of it’s modest brain stem and a 300-neuron brain. One day the sea squirt finds a nice patch on a nearby coral and anchors into it. Then, once it’s safely attached, it proceeds to eat it’s 300-neuron brain.
The moral of the tale is this: “If you don’t move, you have no use for your brain.”
Neurophysiologist Rodolfo Llinàs believes our brains literally evolved so we could better move around and respond to our surroundings. Not for “cool” intellectual stuff like playing chess.
That is also why exercise and the lack of it has such a far-ranging consequences on your physical and psychological well-being. It’s no accident that exercise alleviates stress and anxiety, improves learning and guards against premature deterioration of brain (like Alzheimer’s or Parkinson’s disease).
Most important of all, exercise is free and available for everyone. No need to wait till you can buy an expensive “exercise pill” or gadget in a store.
Go for a walk today. Don’t turn into a veggie!
