I’m walking around the world without leaving home… How? By using a pedometer: it tracks my steps and lets me know weekly the distance I’ve covered. Occasionally, it congratulates me on earning a badge for achieving high step counts (per day) and distance milestones. The exuberant software emoticon that comes with the email makes my day. Earlier on this year, I celebrated walking the length of New Zealand: 1593 km long. A couple of weeks ago, I received a badge for walking the distance covered by the Great Barrier Reef, all 2574 km of it! Now of course I wish I had really been there. On the other hand . . . what is reality?
