is a common greeting that I think makes sense when the two conditions (live long and live prosperous) go together. Otherwise, what good is a long life if poor? And what good is material endowment if died young?
Questions like these concern life and how we live life. They sometimes float in my head while running. And interestingly enough, I do get to sort them out during my run. A dual benefits of exercising the mind and the body from running.
Who knows. Perhaps I will live long and prosperous because of running.
