I am also finding the work increasingly heavy and hard.
That was one of the reasons we ''retired, ha,ha'' to Cornwall. OH said he was getting to old to be clambering about over church roofs all day and as he worked alone had no one to give him a hand lifting things.
I would love an oak framed house, perhaps when we retire next time
Trouble is OH wont pay for labour so I probably wouldn't see it finished
Hope work picks up for you soon Eddie
