I inadvertently (from time to time) practice a different style more akin to high-altitude training. I'll try doing relatively challenging tasks on little sleep or otherwise non-optimal (e.g. had been drinking) conditions. Sometimes I'm surprised by how complex a task I can do and other times which I can't. Either way it's good to know your limits and push them sometimes, there may be a situation where being high-functioning can save you.
