Third hand

My best friend is currently studying Med1, and has started dissecting corpses for his lab exercises, I have to mention is quite an interesting process for me to learn from the images, and understand how my body literally works. He just started digging into shoulder and arm arrangements.

So being drunk on a Saturday evening we decided to try and imagine us having the choice to add a third arm and hand on our body.

After a lot of thinking (involving beers and shots) we decided that the best place to add an arm is on our right side, right under the shoulder.

So if you had the choice where would you add it?
