What is the difference between hiking when you are young and traveling after retirement?

You can go hiking when you are young, but this requires physical fitness as a prerequisite. After retirement, due to poor physical fitness, I need to choose some relaxing and safe destinations for leisure travel.

For example, on August 26, 2018, I met two young men from Ya'an, Sichuan at the 72nd bend of the Nu River. They had been walking along the G318 National Highway along the Sichuan-Tibet Line for 45 days. This requires both strong perseverance and a strong body.

For another example, in mid-June 2017, my husband and I walked more than 10 kilometers from Mizokou at an altitude of 3,300 meters to a snowy mountain pass at an altitude of 4,800 meters. The round trip took 7 hours. If we retire, we will I won’t climb mountains like this anymore.
