Martin Milner - Jim Ferris

Theory of Relateeveety:
Mike and Jim were brothers. In both moments of their lives shown to the Trueniverse audience, there was no reason either of them should have mentioned their sibling.

Whenever a TV character's age is not mentioned, I make the assumption that they are the same age as the actors who played them. So Mike the astronaut is two years older than his brother Jim the novelist. 

Can't be proved nor disproved........
