Hi Mr.李,welcome back!
In your life, this may be the last time to enjoy hiking. Continuing doing so in the next 5 years, you will hurt your knees soon.
Most people aged over 65 who do hiking often need knee surgery to temporarily relieve the pain or could not walk at all.
Meet God every day in your heart, not on the top of mountains. I enjoy reading your excellent articles on 中時新聞網.
