Only loaded a small field of square bales of hay with another person twice and they went under a shed, pretty good workout.
Worked construction in jr high and high school, mixing cement in a wheel barrel, pouring it into 5 gallon buckets and walking them about 30 + feet to dump them was a good workout..
The real ball buster for me was digging holes with a post hole digger for fence post in Oak Cliff, usually you went about 4" down then it was busting rocks the rest of the way down, in the middle of the summer that was no fun but I used the money wisely on beer for me and Boones Farm wine for the girlies
What has my bones and joints barking is a combo of a lot of things, doing a lot of stupid things as a kid and doing things like jumping off of a two story house onto the ground just because we could, sports, heavy weight lifting and being a rambunctious fart, breaking my fibula driving a drunk mini bike, breaking both my arm at different times, broke collar bone trying to tackle a corner of a townhouse while a little bit drunk and so on.
Going to have the left knee replaced now in March, pretty sure the right one will be on that list soon afterwards unless there is new medical procedure or treatment that comes along.
Fortunately for the most part I do not try and bite off more than I can chew anymore.
Almost 67 and very grateful that I do not have real problems like a lot of other folks do!.
