Arms are a wonderful creation.
Who needs four legs?
Like birds – a fellow vertebrate – our arms help us fly into all kinds of new directions.
We use them to do things like, well – play the piano.
But the piano players pain is the pain of us all— neck pain, backaches, sore wrists—an endless litany of woe.
Do birds’ wings hurt when they fly?
Hard to know, but I imagine they don’t. Because birds are using their “arms” as designed by Nature. Birds got the use of their arms right through millions of years of evolutionary iterations.
