I think I've found MY hobby.   I don't seem to have enough spare hours for jigsaws, tapestries, sudoku etc or anything that requires focus.   I'm ashamed to say I haven't read a book in years although I make a new year's resolution to do so every year and yet I never do.  

Here's my new thing... Shaving my jumpers. Satisfying, practical, requires very little focus or financial outlay.  Result.
