This is Bionic Ed... who is really my wife's 99 year old grandfather. He fell last week and broke his hip and shoulder and had to have surgery right away to replace them, and a robotic arm seemed about right to me... Very superheroic, and that's fitting. In real life, Ed fought the Nazis in WWII and played a role in helping to liberate France. He was wounded in battle, recovered and carried on through a long career in the US Army and settled into his role as patriarch of a huge family that carries with it a carnival-like atmosphere. He's a great man, and this is my(admittedly ridiculous) way of paying tribute to him and wishing him a fast recovery.
