Bearing in mind that Dr. Clay at 20,000 years old most had some wrinkles 
and grey hair, I'm inclined to believe that the technology of the 
galactic civilization in Tenchi can easily retard aging to the point 
where humans live for 10's of thousands of years. So even if they were 
just humans, I imagine that Ryoko and Kagato could avoid the obvious 
effects of aging for some time...

Now compound that with the fact that Ryoko is Washu's daughter, and that 
Washu has the ability to alter her own apparent age at will, and that 
Ryoko has enough control over her own body that she can regenerate a 
lost hand in seconds (as long as she has a power source to work from), 
and you can imagine why aging isn't much of a concern for Ryoko. 
Frankly, I would't be surprised if she truly doesn't age at all, as long 
  as she has at least one of the three gems...

As for Kagato...well, he was Washu's student, so he probably had access
to any advanced rejuvenation/longevity technology Washu might have come
up with. More importantly though, it's my understanding that Kagato as
we see him in the OVAs is actually a modification...he was originally
a female, and moved his mind into a (failed, male) prototype Ryoko body,
and so probably inherits as much age resistance as Ryoko does.
