I heard some people say that some skills are unlearnable after a certain age.

Really? That sounds a bit extreme to me.

I guess it depends on how much effort you're willing to put in.

True! With enough determination, I think almost anything is learnable.

Memory Tip
Think of 'not' ('un-') being added to 'learn' — this helps you remember that 'unlearnable' means something that cannot be learned.
