Isnt all this a slight exaggeration
No.
Im sure there were plenty of slim ones too, maybe you just dont reach the mark to get a nice girl in your homeland though, not trying to be nasty here, just surmising (bit like fat bald middle aged Brits who go to Thailand for a bride :) )
Judging by your reply, you're sure of a lot of things you've not an iota of sense about.
Perhaps all those children all looked "healthy" to you because you compared them to yourself. Not trying to be nasty, just surmising (fat people often do that, you don't see yourself as fat so by virtue, anyone slimmer than you can't be either:)
The average Polish girl is still much slimmer than the average Western European girl. Overweight is probably a bigger problem among Polish men.
Put away the white knight suit of armour and stop being a beta male. Being slimmer than some of the fattest women in world (UK ladies) is masking the problem.
That's like saying compared to Central London, property prices here are reasonable.
I hope that it was not the major reason to move. In that case, it says more about you, than about Polish girls.
Let's say that IS the reason I moved, what would that say about me and what pray tell do you think I was trying to say about Polish girls as a consequence.
