I've just watched a programme called The Truth About Getting Fit in which Dr Michael Mosley describes how to get maximum results with minimum effort.
Along with your encouraging words just what I needed to know! (BBC4 iPlayer and parts can be seen on YouTube.)
Apart from going out to fetch wood I've been lucky enough to have a cosy day reading by the fire. It's been blowing a gale all day and the noise of the north westerly wind coming down the glen is still very loud although it was forecast to subside by now. I have however done a little bit of (effective) exercise.
Yay!
