You have told about the hobby of walking in a very interesting way. It was especially surprising to read the story of Naini returning on foot from Tal at the age of 18. The journey must have been difficult and scary at the time, but the experience instilled in you a passion for walking.

I like that you participate in walking not only for your health but also for charity. Walking between mountains, rivers and natural scenery is its own pleasure. Hope you get well soon and can walk your favorite trails again.
