I remember when I was helping to put a sidewalk in at my house in South Bend. I had to bring bags of Quikrete (sp) home to make cement.
I am pretty strong...though my joints don't allow it anymore. The bags weighed 80 lbs each. That number stands out because it was the first weight I'd run into that I couldn't lift (I mean regarding stuff I might have to lift and bring home). So, long story short, my body couldn't lift all that you've lost!!!!
This is fantastic!
