What if someone told you that the man you have always called father is not your real father? What would you do?
Zack, being 27 years, is the one to decide this case. He can reduce all this drama, by voluntarily agreeing to a DNA test, and getting closure on knowing who his real parents are (if paternity is proved). Or he can do a Balotelli.
Set out to correct the world's wrongs and you will most certainly wind up adding to them.
