I have seen many _Dragon Ball_ series like _Dragon Ball_ , _Dragon Ball Z_ ,
_Dragon Ball GT_. One thing remains same is that Saiyans never look aged. The
last episode of _Dragon Ball GT_ shows **Pan** as a grandma, but **Goku** was
looking as young as he was in _Dragon Ball Z_. Why don't Saiyans age?

Why don't Saiyans age?


To my knowledge, they do age, just very slowly in adulthood. This is a genetic
trait, I assume, to reach longer duration of physical demands. They are
designed to be fighters, and longevity of a lifespan is only practical. Vegeta
confirmed this towards the end of DBZ: "So they can fight longer".

From a quick Google search:

From [Saiyan](http://dragonball.wikia.com/wiki/Saiyan) article on Dragon Ball
wiki. (Visit the link for more examples, and a more definitive explanation).

Something else to consider: they stay in their prime longer because they are
full Saiyans, whereas Pan is only quarter Saiyan.

I just have to add something else: Goku shrunk back to being a little kid
during DB GT, right? And if I remember right, he never got the chance to grow
back right away but grew up naturally.  
Might add as to why he looked the same as he was in DBZ when Pan found him.
