Some changes I've noticed since doing this are listed below. Not that they are earth shattering, but just a few things I've observed.
* My resting heart rate fell by about 5 BPM.
* I can now run and walk in my dreams and rarely have the "legs in molasses" thing (if you know what I mean).
* I now wear trail running shoes all the time - a total shift from the old Birkenstock and whatever shoes I wore for years before.
* My town has a number of fun, curious little sidewalk shortcuts between neighborhoods that I did not know about. They aren't secret, just not obvious at all.
One of my favorite things to find in Santa Barbara are old concrete stamps marking which company/contractor poured that section of sidewalk. Often these are 100+ years old. I've currently found ~25-30 different ones.
I know exactly what you mean. That’s fascinating that it went away with more walking; maybe the brain is now better able to “simulate” walking?
