later I'm gonna tell you all the details, if you respond me.
I must say that when I saw your first post a few days ago about whether you looked Polish, I assumed you were American and interested in your ancestry. Since then, I've realised that you actually are
Polish but you want to know if you're 'truly' Polish, as in your ethnicity, is that right? What I'm still not clear on, is whether you are upset or worried in some way that you might not be 100% 'Polish' or whether you're just interested. I can't see any reason to be upset about having a bit of a mix in your genes.
As for people stealing your organs, how could that happen? Do you mean the testers sell your data to governments who put it in a database and then if you go to hospital for a routine procedure they snatch a kidney while you're under anaesthetic? Can't see that happening in the developed world. I know China has a reputation for that sort of thing, but I reckon you're ok in Poland.
