Surely, anyway, a working day of eight or nine hours which is not split by a nap is simply too much for a human being to take, day in, day out, and particularly so in hot weather.
Now it is human nature to want to eat to ones fill when hungry, to want to warm up when cold, to want to rest when tired. These all are a part of people's emotional nature.
We can also cut by heat - heat punch. And we also can cut by cold - extreme cold. When you cut with heat, it makes a mark. With cold, no mark. It depends on the fabric.
