It sure does make a difference. I have a retaining wall on the hillside at the edge of my patio. I can stand on the patio, put supplies on the concrete blocks and reach over to weed the garden, water it or pick produce without bending over on most of the plots.
It sure makes a difference not only on the back, but on motivation.LOL
I can appreciate a number of things now that I didn’t when I was younger. :)
