More on this to come plus some catching up to do. Three weeks ago I discovered, too late, that my backpack with computer and passports was mislaid. Most probably stolen outside the London hotel as we waited for a cab. Such events are quite life shattering, not to say expensive. Yes I had backed up but several weeks files are nonetheless lost. Yes I did let my defenses down. Would I have done so in Venezuela? Hardly likely, so why London? I think I know the answer and I keep kicking myself.
Replacing passports was not as bad as I anticipated but still a very big hassle. The computer is the next priority.
