Hoist
If you have fingers it's easy to hoist things above your head. If you don't have fingers, well, it's not so easy.
Hoist the sails! Hoist the anchor! Hoist a baby! All of these situations are easier if you have a ton of working fingers. (The more the better.)

Today, you have to hoist so much stuff. "Ah!" (あ) you say, "So much hoisting to do." Better get to it!
Imagine hoisting things over and over again. Each time you spot a new thing that needs hoisting, you say "Ah! Something else to hoist!"
