Just finished 500ft of 6ft privacy fence in 51/2 days by myself and I'm almost 74. My Dad always said it's nothing but work. As far as aches and pains go, I don't know if they are any worse than they have ever been. As a young man from about 16 to 25 I use to break horses and have hit the ground so many times that I thought we were cousins.
Dats wat Imma talkin bout, DRIVE ON !
