Wish I could still enjoy life when getting old

There was one time I worked a tour guide for a group of people from USA.In our schedule,I guide them to Yuexiu Park because they are very interested to see how our Chinese life is naturally. So I took them there and they enjoyed the whole trip,especially the part where many old people gather together and sing songs,play instruments etc

Even though they do not understand what they sang but they still enjoyed the happy moments. And they told me it was very nice to see people enjoy nice life here,especially for those old people when they get old and have nothing to do.

So by that time,I am thinking to myself"Wish I could still enjoy life like they did when I am getting old someday!"
