The hiking gets progressively more challenging as the days go by and we venture further and higher into the Himalayas. The air gets thinner and the terrain becomes steeper. Our lungs strain to get enough oxygen to our bodies. By the end of some days, my calves feel like lead and my knees are like jelly. Many times a day I briefly wonder why I am putting myself through this physical ordeal. Then I look up and take time to appreciate the panorama, or smile to a local child who offers a friendly greeting of “Namaste,” and all my pains are forgotten.
