You are never too old to learn a new language
i went over to visit my grandma the other day and she saw me on my phone practicing german and she was like "whats that?" so i told her its easy and fun and you can learn (the basics of) a new language on it. she got on her ancient computer and set up an account and now she is better than me.
Last year I was turning 40 I read an article that said "If you are over 40, forget learning a new language - that ship has sailed' and it annoyed me so much that I decided to learn Japanese. Well done to your grandmother! The fact that she's stayed curious and kept her desire to learn will keep her young :)
and I have turned 41... forget the article, it is false :) When I have started to play the piano, I was in changing groups, because my job was in shift work. (What is the way to say, that a person works in different times?) One of the group consists of people learned the piano with an age over 60 years. And they have played the piano very well.
Wow! Sorry for getting out of the subject but I couldn't help to notice your streak and the number of languages you have learned! I'm very impressed and curious, are you able to have at least a basic conversation with them? Don't you get all mixed up?
I hope one day I can achieve what you have done, I would like to learn many languages but it feels like forever to make any progress, especially while dealing with other responsibilities.
