Safe bet that Kal is probably no longer his perpetual 29 years old. I remember Clark was listed as being 34 years in his obit following 1992's Death of Superman storyline. By the time Flashpoint was about to begin in 2011, he may have added a physical year or three.
Then New52 happened. Then the Smiths showed up. Then Nuperman and Superdad merged.
I'm trade-waiting but don't mind being spoiled here.
Bottom line - how old is Clark now in-story?
