Question
Which one is older between twin twofold?
First born or other one?
There is a rumuor " second one is older". Is it true?

Answer
I don't understand what you mean by "twofold". If you're asking which twin is "older", technically speaking - twins are  created at the same time since the two babies came from just one fertilized egg that split completely during its first division. So, both twins were created at exactly the same time. However, convention usually assigns which twin is "older" depending on which one comes out of the mom first. The first twin to be born is considered the "older" twin.
