Oh, related to the story given by the frog.
I practice frequently walking down the road with my eyes closed. It livens up a walk which I've done for the last 17 years.

At first I could only go about 5 steps before having to open my eyes, but now I can walk about 10 before checking for lampposts.

Once I walked into a hollybush, but it was okay, as I had my eyes closed.

Do you "reverse blink" when you do this?
You know, open your eyes for a brief fraction of a second and then shut them tight again as fast as you can?

I used to do this as a kid, and after a while you can do surprisingly well only seeing for 1/10 of a second every 3 or 4 seconds.

I have to admit I do the same
There's a strange thrill to be had walking with your eyes shut.

Does this mean
that you have only advanced 5 paces in 17 years?

Try...
...riding pillion on a motorcycle in a helmet with the visor painted black.

It's ace. :)
