You can picture exertion as force being pushed out from the inside until it shows. A body pushes effort out and the person sweats, breathes hard and sits down afterwards. Someone with authority pushes that authority out into a room, and what happens next is decided for other people. The thing being pushed changes; the pushing is the same.
exertion 可以想成「把裡面的力往外推出去，推到看得見」這個畫面。身體把力氣推出去，你會流汗、會喘，事後想坐下來。有權力的人把權力推出去，房間裡的事就照他的意思發生。推的東西不一樣，但推這個動作是同一個。
