Thumbs up is good. Thumbs down is bad. Especially, if you are a gladiator. Then it can be understood.
To be honest, I am glad to have paws. Top left: drawn own left hand. Thumb slanted down three quarter. Gout? Three quarter good? Half good?
Top middle: drawn own right hand, seven eighth straight. Gout as well? Almost completely good?
Top right: left elbow on the table, shoulder to the left, hand down, luxate arm. Watch out for a slipped disk!
