Puzzled

So I've found that if I get a solid hour or two of exercise per day, I don't need any antidepressants. I could just do a good workout in the morning and another at night. But I'd really rather just have physical activity be a natural part of my day. If I had a job, having one about 4 miles away that I could cycle to and from would be ideal. Or having a job that naturally involved a fair amount of activity. But for the last two weeks (and the next few, I'd guess) this is how I have been getting my exercise.

The chickens "help out" by eating all the juicy worms I dig up when I remove an inch or two of dead grass/dirt to set the stones in. They've never eaten so well in their fluffy little lives. 

I can set 20-50 stones per day, depending on how large the stones are (they vary from about 15 to 50 pounds- I have Jon move the occasional 75 pound monster) and how easily they fit together. It's like the world's heaviest jigsaw puzzle, with no picture on the box to guide you.

Putting in the stones will help a little bit in reducing the water bill, a bit more in reducing the amount of mowing we need to do, and rather more in making the back yard look like I meant it to be like that, rather than just "Eh, I didn't know what to do back here, so I left it to the bermuda grass." I suppose I could try to make a job of it, but can you imagine the business card?

Two hours per day, maximum.
