I've never lost my glasses, but I always wonder how I'd cope as a visually impaired traveler - maybe I'd see more. Least useful - any question. I never found out what it was. I'm not too worried about this. In other words, it's better to see a few things well, than a whole lot superficially.
Travel broadens the mind' is definitely a clich , and a highly debatable one at that.
Traveling is something my wife, Pauline and I enjoy doing together. Or maybe one of my children - they ask such good questions.
