Started in my sixties too. Slower than a younger learner for sure, but I got to a genuinely comfortable conversational level over time. It’s possible, just don’t expect the speed of a twenty-year-old.
I'm 63 and everyone says older brains can't learn languages, which is discouraging before I've even started. But I don't want to live here for twenty years fully dependent on English and my spouse translating. Has anyone genuinely got to a comfortable level starting in their 60s, and how did you go about it?
