Walking is the best form of exercise. It is good for the upper respiratory（与呼吸有关的）system and the legs. It helps us control our weight and blood sugar. Walking is also a good way to help you make more friends，bringing chances to see new things and meet new people. Personally I try to walk at least 5 miles daily.

As well as walking，I also cycle around Xiamen. Cycling is great for weight loss and helps to build stamina（耐力）.However，cycling does not allow for the same level of social contact as a walk. It is for this reason that I would strongly suggest that you try long-distance walking if you want to be physically healthy. I originally（最初）started walking around Xiamen because I didn't have a car，but I soon started to enjoy the walking for its own sake.

I have also made many friends during my walks. It's not uncommon for my 5-mile walk to sometimes take as long as 2 or 3 hours，because I stop to chat with different shop owners along my route. These days，if I skip my walk for even one day，the people in the shops may want to know why I didn't come.

I' ll never forget the first time some people followed me when I was walking, and asked if it was okay for them to walk with me. I really didn't know what to say, so I just replied that I didn't mind. I have been invited for lunch, dinner and sometimes just to sit and drink tea with total strangers. There is nothing more pleasant than walking past a schoolyard and hearing all the kids say hello to me.
