A little over five years ago, I noted that I had made it up to 31 countries visited. Here "country" is a very loose term, but I am using the list maintained by the Travelers' Century Club, an organization open to those who hit 100. Since then, I have visited...no more countries. So I'm still at 31. What to do? Maybe visit more countries, yes, but in the mean time, let's make some graphs.
Above you can see the rapid growth I had in countries visited in the last decade, and the leveling off since. Below, you can see my countries/year. I start just before I add my third country (Canada) in 1987, or else it would look pretty silly (my average of 2 countries/year for my first year was hard to keep up with).
