A simple subject covered by Ptak turns into an eternal debate which was first: the egg or the hen. :_):):):)
Embarrassing, simple answer, but for you, a major difficulty. Egg, of course. Why would you even ask? Fenix would have an answer in five seconds, ten maximum.
But then, you are not Fenix, not even close; she is playing on a different level, and you can't even smell her dust. At least wish her Happy Women's Day, you primitive caveman. Without her help, your stupid puzzle topic would expire before you even start it Sh*it, I am not sure if it's possible.:::)))
