I'm now close to having two news knee's after 4 years of operations. Life is a challenge physically and mentally, something I've noticed is that when I'm feeling low life will give me an lesson .. reminding me that it could always be worse. Case in point the chap on the right, lost his left leg thanks to a drunk driver running into the concrete wall he was sitting on, died twice in the ambulance and once on the table. Made my day with his sunny disposition and can do attitude.
