Mike went out tubing with the kids. I don't have a picture of him actually tubing because I wasn't out on the lake at the time - which is possibly why he got away with it. We don't notice the aftermath of his cancer surgery in the daily grind as much as when we are out doing different things... like tubing. Mike noticed pretty quickly that he did not have the arm strength to protect his shoulder from the jarring motion. He opted to "eject" from the tube by letting go almost immediately. In the process he noticed the neck strength he had lost when he bounced off the wave in a whiplash motion, because he lacked the strength to hold his head like he used to.
Note: He did not injure himself more than getting a sore neck - and he learned a lesson. Sometimes it is important to realize that there is still healing going on. Sometimes it is important to remember not to do crazy, silly things that could impair your progress.
(Sure hope Mike is reading the posts today. )
