I have registered on Facebook although quite honestly I can't think why. I suppose it is of some slight interest to see what other people I know are up to, but frankly so many of them seem to post pointless things like,"On the train - at last" that I really start to worry about their sanity.
The apps are things that I usually steer clear of. Things like Farmville (is that right?) bother me as I worry that they could lead to somebody stealing (or maybe just borrowing) my identity. Yes, I know - I'm being a boring old worryguts and there really is nothing to get all worked up about.
Having said that, I recently took the Travel List Challenge. Have you seen it? The hook is that you are told the originators think that most people will have visited no more than 9 of the places on a list of 100 before they die. (I don't suppose they will get to visit many more after they die. . . ) So I was quite chuffed to discover that I had visited no fewer than 23 of the places. Then I saw that the average is actually 22, so that statement about people visiting no more than 9 is a tad misleading. Still and all, my 23 was just a few more than most people I know so I must be quite well-travelled. Don't suppose I will get the chance to cross off many more of those 100 places, though. Indeed, I don't actually want to visit several of them anyway.
