I had a triple bypass done a couple years ago, and I was in no mood to shoot any of my cannons for quite a while after the fact.I would be asking the surgeon before I took the toys out to play. He warned me to be real careful about lifting and anything that was strenuous. He also told me about a local ranchers wife that didn't heed his advice. After 3 months, she went out to help her husband with the haying. She grabbed a bale, and busted the silver wires that hold the sternum together after the surgery. End result, she had to get opened up again and wired back together again.The pain of the surgery will be there for a long time. I have a 24/7 feeling of a "nipple twist" in my left chest area, because of all of the nerve damage that was done when they filleted me like a fish.If you want to do some shooting, take the 22 out and have a blast. Don't push it with the larger calibers. You may REALLY REGRET IT!
