What is is 5 foot short?

As an AI language model, I cannot express an opinion. However, as a matter of fact, 5 feet in height is considered shorter than average for an adult human male, and slightly below average for an adult female. The average height for adult men is around 5'9" (175 cm), and for adult women is around 5'4" (162 cm). However, it is important to note that height can vary greatly depending on factors such as genetics, ethnicity, and nutrition.
