Being a deckhand on a Quinlan boat was very much a strong back, weak mind kind of thing. Pick up box here, put box down there. Rinse, repeat. My manny was much stronger than a native, and I didn’t get tired, but overheating could be an issue, so I didn’t push it. Every once in a while the entire crew would take a fiver in the water to cool off, which told me I wasn’t the only one with that problem.
