Thanks so much, Bicho, an enjoyable and informative read...

I have been living in Vietnam for 12 years and I can't speak the language even though I'm exposed to it daily.

I know a few words and can't really construct sentences yet. I haven't consciously tried to learn it.

I wonder now, what activity I could introduce into my schedule, 30 min a day, that could possibly release any or all my subconscious vocabulary?

I will dig deeper into this.

Thanks for sharing, I really appreciate it!
