Ditto on what Ross said, unless you are like me. I couldn't take 5 or 6 steps without stopping and trying to get my breath. I tried to keep up some activities but most took great effort. Eating was still enjoyable so me and the wife spent some quality time hitting some places we had never been. Spend time with the family.
And don't forget to "vent" here. We have many ears and mouths (or is that fingers) that can help you through this walk. Our prayers and good thoughts are coming your way on your pending walk and try to have someone post an "after action" report on your successful surgery.
May God Bless,
Danny
