The saggy arm meat that wobbles like a fat man’s leg when you write on the board, 50+ math teachers have it and it's a disaster

My arm looks like a melted cheeseburger when I write equations

I explain math and my arm shakes like it’s been through a blender

My fadubuda is so bad, my students laugh every time I write a problem
