He does not have any stamina. He should be wiped out by November, as in exhausted.
I had a family friend who headed a big corporation when I was in my teens. He had more time off than he worked. This big shots don't work much, And when they do, it's not work like regular people do: teaching, putting out fires, stuck in an office working with numbers or customers, etc. They play work, glad hand with other Masters of the Universe, take their copters around to meetings where they are treated like gods. Not like us.
