Mr Ross remembers (the days) when he was poor.

Why does Percy Ross give people money? When Mr Ross was a boy, he was very poor. He worked hard and now he's a successful businessman. But Mr Ross remembers when he was poor. He wants to help poor people.

(True Stories in the News, Sandra Heyer, Longman)

I’d like to know whether this sentence--Mr Ross remembers when he was poor--is correct. I mean if it’s necessary to change it like this.

Mr Ross remembers the days when he was poor.

Thanks, Piscean.

I wonder if my version--Mr Ross remembers the days when he was poor--is also correct.
