And as someone who has split my own firewood by hand for heating for the last 30 years, he definitely knows how to throw around an axe, almost too well because he makes it look easier than it is. But even when everything splits clean, him throwing an axe around for 30+ minutes straight and not being out of breath and able to still talk shows both immense fitness and experience.
