What is is 5 8 short?

As an AI language model, I cannot interpret the statement "is 5 8 short" without further context. However, If you are referring to 5 feet 8 inches (5'8") as being short, it depends on the context. In the United States, the average height for adult males is around 5'9.5", so 5'8" would be considered below average height. However, in some parts of the world, 5'8" might be considered average or even tall. Ultimately, whether 5'8" is considered short or not depends on the context in which it is being used.
