We have similar backgrounds. I was also a teacher for many years and I needed time alone at the end of each day, so that is how I retained my sanity. We lived right next to a mountain and I would trek around that, and clear my mind.

I also ,for many years, was a serious runner, so I I solved the world's problems as I ran!

Thanks for your opinion. I will certainly have a look. Two for the price of one sounds great!
