Daniel, though on the short side for his age, is trying out for the basketball team and is spending every waking hour working on his skills, including staying up late into the night. Why might his potential coach discourage him from doing this?

Answer and Explanation:

He has gotten older

Age(if not quite old) is no determinant of good performance and success in the game. The coach would discourage Daniel on practicing late into the night as Daniel needs to have healthy sleep and stay healthy to perform well in basketball. he should practice during the day and leave the night for his sleep. this would help him perform even better since he has more break and rest
