At the beginning of dragon ball, goku is 11 years old, he's 4 years younger than bulma (15 at the time) in battle of gods she's "37" which means goku is 33, but he isn't... When the 21st world martial arts tournament is happening the announcer asks goku his age,'goku says 12, so a year has passed, that is acceptable. 22nd world martial arts tournament a year has passed so goku is now 13, apparently (according to the dragon ball wikipedia page) the 23rd one takes 5 years after the 22nd one because it says that goku is now 18, but it also said 3 years had passed so goku SHOULD be 16...
Dbz takes place 5 years after the 23rd tournament, so goku is 21 (23 says wikipedia) then after the frieza saga goku takes 1 year to get back to earth in the shuttle pod so he Is now 22, then 3 years pass before the androids arrive so he is now 25, then he goes in the hyperbolic time chamber for a year, now 26... Goku then dies and stayed in other world for 7 years if he aged in other world he WOULD be 33. But he doesn't so he is still 26 years old, and when battle of gods happens, 4 years go by so goku is now 30 (would be 37 which is what BULMA IS SUPPOSED TO BE!) and by that logic that means bulma SHOULD be 41. But the movie states 37, so thanks to my research I have rustled some Jimmies and made goku younger.
