Fuel. That's what keeps us going. That's what keeps the entire World going. Look up at the sky and we see our Sun. We feel its warmth millions of miles away and that warmth comes from the burning of the Sun's fuels.
Here is a photo of two fuels used to keep us climbing at the gym. I'm not sure of the octane but the red one looks a bit more powerful! This photo is straight forward and concrete if not a bit trite. What's a little harder to capture in a photo are the other "fuels" that keep us going at the gym such as friendship and camaraderie. If we could bottle that and distribute it, I think we would be doing even better as a society as a whole. In the meantime, I'll just try to convince people to come to the climbing gym for a little drink. Cheers.
