I am a big fan of physical labor. To me routine exercise at a gym is valuable time wasted. This is especially true because the nearest gym is an hour and a half drive roundtrip. Exercise includes physical labor. If there is no physical labor available, I generally do hill walking. My driveway is very steep and all I need to do is walk out my door.
One of the tasks I worked on during my second and third year post op was building an underground shelter. Tornados struck about 7 years ago, just after I retired. The tornados did a lot of destruction to my property but spared my house. My house is a one story without a basement and there is really no place to take shelter in the event of another tornado. So I decided to build an underground shelter from an intermodal-shipping container into the side of my hill. Of course, if I build a storm shelter, it should also be a root cellar. And if I go to the effort of building a storm shelter/root cellar then why not go through a little extra effort and build it for Come-What-May, including asteroid impacts, nuclear war and nearby supernovas, etc. So during each of those years I moved 100,000 pounds of gravel by hand along with around 60,000 pounds of concrete blocks.
This year my wife wanted me to build a playhouse for the grandkids. I decided to build a log playhouse and also get some of the grandkids involved in the effort. It uses 160 landscaping timbers. With the loft, it extends around 16 feet off the ground. I had RNY gastric bypass surgery over 4 years ago. Without the surgery, I could never perform these tasks, especially since I am approaching 70.
