Although we grew up learning fatigue risk management, we likely didn’t realize this was what we were being taught by our teachers and parents. Our earliest teachers taught us that after lunch, we took a nap so that we would be alert afterward. Our parents used the same nap-time theory on us at home, and told us napping was so we would be ready to go outside to play. (In reality, our parents needed a break and were managing their fatigue.)
