I needed to put nuts on Jay bolts to put in the concrete, and it was a mindless job, so I thought while I did that I would multitask and write here on the forum. Boy, we I in for a surprise. I pickup up one of them, and I had black oil/grease on my hands. So I was not going to touch my computer while doing that. I found a pair of disposable gloves to wear to do that task, so that I could keep grease/oil off my hands! So I concentrated on putting the nuts on before writing here, and now that job is finished!
