My arms ache. I have been painting my hall, the woodwork with a brush and the walls with a roller. Years ago I plastered a wall and I couldn’t believe how anyone with arm muscles any smaller than Popeye’s could do such work professionally. Today I saw these guys, and felt humbled. These are full-length scaffold planks being lowered down the face of a building in Edinburgh’s George Street this lunchtime by sons of Popeye. The speed at which they lowered them was awesome.
