I couldn't agree more. I have been a walker since my early 20's and never bore with it!!!!!!
I always have someone with me and have always have my German shepherd. (grew up with them.)
When my kids were babies I taught them abc's and 1 2 3's while walking and my daughter picked up some French.
We also study trees and nature while walking only stopping occasionally.
Another benefit is if you go with hubby someone is there to hold your hand
