For sixty years I have averaged about four hours sleep per night, and I've simply gone along with that.

When I was young (yes, I was once) I used to sit up until 2.00am working on the most intricate and difficult parts of my model ships. The rigging etc.

Now I do the editing of photos and music till the same hour, with regular forays into Mudcat.

When I go to bed, I'm asleep in seconds, and dead to the world until 6.00am, when I wake, and then drift in and out until my wife wakes, about seven. Then we both get up and attack the day.

With that level of sleep you don't have time for insomnia.
