It may be that I am not getting any younger, but one of the delights of getting home was sitting in a chair to write, use a radio and do stuff. I think one of the first things our ancient ancestors must have done is drag a suitable log into the cave to sit whilst whittling a mammoth tusk. Much more comfortable and better than living at/on ground level where life is one long plank or press-up exercise! At one of my camp sites I found a perfect size log and did just that. Luxury.
