On burning fuel.

It's a brutal world out there for those of us that drive cars on a regular basis. The cost of fuel fluctuates more than life itself, often to the point of no return in terms of our bank accounts. Fuel goes in, fuel burns. And that's that.

That's also how our bodies work. Food in, food burns...and then we move and shake through our daily list of activities. Lucky for us, often in contrast with our cars, our bodies are quite the machines. Efficient machines, I should say. Take a look at this comparison if you don't believe me.
