hello
I'm writing a paper on teaching EFL to adults.
I've been looking for some resources -books, articles, etc. I've got some methodology books but it's all general in them. I have trouble finding more detailed/specific information.

My age group concerns so called " 50+ students" (those older than 50)
and my task is to write how social life, career/job, family life influence language learning.
And I can't find any info on that:((

could anyone help me, please? I would really appreciate any suggestions, tips on how to/ where to find those things

thank you
