Surgery machine practice with dices to stack

Hi, I'm Nitzan, a surgeon living in Spain. I follow your videos, love them. This is how I practice for some of my surgeries. I'm a plastic surgeon, we do complex reconstructive surgery, using microsurgery. In this case, I am practicing for laparoscopic surgery, which we use in some cases for minimally invasive abdominal surgery. In this video, I am simply working on my technical dexterity, using a training module. Thanks for all your work! I also sent you a video of my dog once :)
