barefoot

I don't doubt that barefoot walking does a lot for your health. You're making a few great points in your video. Those pressure points you're talking about, though, are called ツボ here in Japan. I have some experience as massage therapist and can tell you, that's just marketing based on old beliefs. Stimulating your feet does a lot for relaxation (which then has other positive effects), but all massage is more of a prevention method than therapy. Tldr: if you have problems with your eyes, see an optometrist:)
