Yep, that's the responsible ting to do; it's important to have the ability (judgement) to know what's required and what is not. I often push back things in my own life (like sleeping today) as I tend to be good at prioritising. Of course, that will catch up at some stage so it's also important to know one's limits.
Even the fastest Formula One car needs to come into the pits for fresh tyres, fuel and general service right?
