给定一篇文章并指出其中的拼写错误。


以下是一段英文文章：
It is common beleif that a perrson should drink eight 8-ounze glasses of water every day to stay hydratd. But is this reaally truue? Some scientists have challenged this advice, suggesting that it may not be necessary to drink so much water and that different people may need different amounts of water depending on their body size, activity level, and climate. They also argue that other drinks and foods, such as tea, coffee, fruits, and vegetables, can also contribute to the body's hydration needs.
The spelling errors in the text are: "beleif" (belief), "perrson" (person), "ounze" (ounce), "hydratd" (hydrated), "reaally" (really), "truue" (true).
