Following up from this question I started to wonder how old Mon-El's parents are:
We know Mon-El was stuck in the Well of Stars for some unknown amount of time, which is why he didn't age significantly - in fact we see him on Daxam and he looks just the same. So he seems to be in his 20s (as is Chris Wood with 29).
We also know that he left Daxam 34 years before he arrived (2016 - Season 1 finale / Season 2 opening) as the title card from the Season 2 Finale (2017 - one year after his arrival) gives us a clear point in time when Krypton exploded:
Furthermore, the ages of the actors playing Queen Rhea (Teri Hatcher is 52) and King Lor-Gand (Kevin Sorbo is 58) are known and we are shown that the characters are surprised when they arrive in the Sol system and discover that they feel different and stronger due to the yellow sun.
Additionally they talk about having been searching for Mon-El all these years, so I think suspended animation can be ruled out (but I might be mistaken there).
Finally it is no secret that Daxamites are promiscous, but still, how could a pair of 50-60 year old people have had a 20-something son 34 years ago?
