So....Lately my wife has been working me like a borrowed tractor...lol...one of my many to do list things was to re-seal the whole exterior of our house....so two weeks into it...tired, aching muscles and in general worn out....I was thinking,...man this didn't use to take such a toll on me like this....just getting old indeed....then I realized it not the work wearing me out so....it is the..."go back trips.." to go back and get what I forgot....two or three times the mileage in steps...LOL
