I am still active and don't shun physical work. I often buy Sand and Ballast in 56lb bags at the local builders merchants and Although on a trolley- It still has to get pushed out to the van and then get loaded. Last week I did my usual trip to the store and as I paid for the ten sacks they asked if I needed a hand loading up. "Yes Please"---The one that came to give me a hand was a young girl and I would put her build as XXXL. After 2 sacks I told the girl I could load on my own and I think she was grateful. She was puffing a lot more than I was.
