Agree with that I would say anyone who has a death wish on here have a go at that!!!!Whilst on the subject of low level fires, I thought I'd post alink to the Winter Scout Pit, which is basically a Scout Pit, with a fire at one end.
Another way of describing it may be that its a large Dakota Fire Hole, with the air channel dug to accomodate an adult!
First link is to the Scout Pit build, the second is to illustrate the Winter Scout Pit.

I'd have thought that sleeping with the head facing the direction of the air hole and feet towards the fire would be better, and the entry point above the head!
Kind of reminds me on the crematorium.
