The guys are more physical, meaning they carry the bags, or the plastic bags from all your fruits and vegetables carrying you around to go inside the house.

When your body its tiredsome, that situation of their edgy might heighten, but as they do that more often, if without you.....they carry their own life, to carry more works on that life they pursue at, sometimes, they build a house, sometimes they build a yard, sometimes they nail on every garage. 

They carrying the suitcase, their fire department gear, or those police stuffs.

Those things makes the body tired. They rest they get up. When you put your 4 limbs on the working mode, and focus on that moment, to know why you are doing that for....its for the evolution of your trajectory to reach somewhere, you will know why you will insist to work til the days you die, really.

Especially this time.
