A tuba player holds a weighty object and breathes deeply.
Exercise is boring. Everything is boring that does not happen in a chair (reading and writing) or in bed. Sculptors and painters and musicians live longer than writers, who exercise only their fingers with pen or on a keyboard. Sculptors chisel or weld or mold clay. Painters work standing up. They drink quarts of cognac every night but return to physical activity the next morning. A tuba player holds a weighty object and breathes deeply. Even a harmonica requires more fitness than writing.(Context for the tuba reference.)
Also, Donald Hall quotes Henry Moore quoting Rodin quoting a stonemason:
Never think of a surface except as the extension of a volume.
Stupid Human Tricks!
I made a simple countdown timer to count down to 00:00:00. You can pass in simple RGB colors for the background and foreground for the start and once it hits zero, e.g. this link. See my devblog for more info.
