(Note: Henning Ohlenbusch has a YouTube Show called “Henning Goes For a Walk,” in which Henning goes for a walk. He even sells tee shirts that say “I’m Going For a Walk,” and I want to buy one. Anyway, this is a commentary on Walk 384, June 4th, 2026):

During the walk you filmed yourself taking on June 4th, 2026 (Walk 384 of the YouTube Series “Henning Goes for a Walk”),  you speculated on your future self 30 years from now travelling  back to the present, which 30 years from now would be 30 years ago.

This got me thinking. In particular, I started thinking about the whole notion of someone traveling back in time 30 years. It started yielding all of these permutations.

One was that maybe very soon, I'm going to have the chance to travel back 30 years in time, but there's a catch. I'm not going to have any memory of that time I lived past the moment to which I go back. All of the life between that moment to which I go back and now will be lost to my mind.

Perhaps this has happened several times before, and it is only here, near the end of this 30-year period, that I start to realize that I've done this several times before. and that I have no memory of it.

Or perhaps on June 4th, I started for the 20th or 200th or 2,000th time, living the life that I sent myself back to when I was 90, and said to myself, this time, finally this time, I would remember that countless times before when I turned 90, I sent myself back 30 years, but had no memory of it.

If only I had that memory, I kept telling myself, I would prepare a bit for the next time.

Except this time, because I saw the movie of your June 4th walk, I know for sure that when I hit 90, I'm gonna go back, again, to this time. And this time, I’m going to have more to work with, because I’ve been writing two letters a day in longhand every day, so that the next time I go back, I'll refine even more this compact style of writing I’ve come to love so much…and I’ll know that I’ve been here before.

So thanks for the illumination. I think I'll go for a walk.
