Why do people twist CPC's?

It's quiet in here isn't it, one could nod off quite easily.

It is not as quiet here as Netherworld whence this post originated.

I remember seeing the twisted earths (earth continuity conductors) above junction boxes when I was younger. No screwed terminal or even a Scruit, just twists of conductor. I thought nothing of it at the time and considered it normal. Even the 3 core or 7 core tinned copper stranded earth wires were just twisted outside a junction box. That was probably accepted practice in the 40s, 50s and 60s.
