Thanks for the reply Pgkevet.
I don't think that I lack imagination or have lost my youth. I gave up a lucrative professional life, sold up and moved to France to live a very activate and simple life. I use all that I have access to , be it sand that I dig from the lake shore in the summer, stone I gather or the timber that I fell for fuel nod building.
Given our climate is probably warmer than yours and we do not have to flee 24/7 shopping or the intense nod persistent pressures of urban or rural life in the Uk I have no need to live on a desert island.
