Would you read the following?
Remember when you were a kid, and it seemed as though there was too much time? I can remember, at around age 9, having so much spare time, especially during the summer, that I could afford to spend entire days on activities such as coloring my entire stomach blue with a ballpoint pen, or conducting a scientific experiment to see exactly how many candles the dog would eat before it started walking funny. Well, those innocent days are long gone.
What does this phrase "entire days" mean in this case?
A reference book says this means "all of the days and every daytime during the summer," or something like that.
Is that so?
Thank you very much in advance for your help on this.
