I think you probably have a good point. It has crossed my mind that I spent so long waiting for someone to travel with, then caravanning around the UK because I had a job with a caravanning magazine, and not going overseas because the blasted non-existant fungal infection makes things difficult. Now my husband can't walk very well because of his foot, and I can imagine that the only way I'll be able to explore the Grand Canyon is on my own. And if I leave it too late, I may not be able to do that. I've already had a reality check on my romantic notions of trekking the Amazon rainforest.
