I guess it was just me over-doing it. It didn't feel like it was getting enough momentum up.... so I eased it past compression with the lifter, then gave it a walloping great kick... and when the pawl slipped, I was hoofing 116kg of me into just my knee joint when the lever bottomed out. Snap.
Meanwhile, I got a lesson in tenderness last night. I was turning down the blanket and sheets of my hospital bed and I leaned against the rails on the side of the bed. Holy bloody mackerel (not the words I used). Brought tears to my eyes, it did. No damage though... no weeping from the wound anyhow.
That, and a small slip where I fell against the wall.... just the right sort of reminder to take it bloody easy.
A man should only do the work that is required of him. To do more is a form of greed.
