I would like to say no but I think there are different factors. So, surely, when you're young you learn faster and I think especially because there's nothing else that's occupying your mind. You're just studying. Maybe you go to high school or even university so it's easy to take on another subject. So say I want to learn French or whatever, so it's just more similar kind of thing learning but once you start working and your brain is not used to that kind of input any more, I think then it becomes more difficult.
