One local example,A man who lives down the road from me with his wife has always had a caravan and has gone on trips around Australia every year, year after year thats all they did,it was his retirement dream.
All of a sudden his wife gets this thing happen in her legs where they physically swelled up went red and tingled numb ,she cant feel them any more,doctors , specalists etc ,test after physical test ,nothing found ,but she cant sleep with the discomfort or walk without aid and so they arent going on holidays any more.
Eventually he gives up and sells the caravan,wifes legs heal up.
Legs are linked into the subconciuss part of the mind that want to or allows us to move forwards in life; that goes for 'forwards in every area'.
Ok get the fire going, tie me up.
