The arms allow the hands to move, for us to pick things up, put things down.
We often think about moving our hands, with little thought to the arms which guide and navigate the hands.
The arms are responsible for us inviting a hug or for us keeping our arms down tight to avoid the hug (or if you are unlucky like me, you still get a hug anyway – arms locked in and all you can do is hope it is over soon!)
Enjoy this observation focusing on the arms.
