One night, on a drinking holiday, I was ran over from the back (while on the sidewalk/side of street, mind you) while on my nightly walk, and crippled permanently by a hit-and-run driver that was never found. (C5 level non-complete quadriplegia)
I miss my walks immensely. They used to put my mind at ease like nothing I have found since.
No point in this comment other than to express my envy towards those can enjoy such a hobby still , and to express a bit of loneliness and hard-to-reconcile personal emotions when told the benefits of walking.
I know, already! I wish I could!
I was very fit my entire life through very little additional effort other than nightly walks & some lucky genetics -- although unfortunately those hobbies landed me into a net-negative position -- I suggest the hobby to anyone that has a few minutes to spare a day.
I hope that pedestrian safety and road design continues to improve.
