Re: models: fundamental question referring to member variables

Your example and explaination I understand, but what about using other
classes as member variables and not just simple values.
Let me give you an example:
The user table has a column 'birthtime', but in my page i want to show
the age in years and days of the user instead.
So i have a class 'Age':

Pseudocode:
class User(
private $Age = new Age());

So when i retrieve the data of the database i first need to set the
birthtime:
$this->Age->setBirthtime($data['User']['birthtime']);
to be then able to access to calculated years and days:

$user->getAge()->getYears();
$user->getAge()->getDays();

The same the other way round:
If i want to randomize the birthtime of the user with my solution i am
able to do it like that:
$user->getAge()->randomizeBirthtime();

But when i want to save the user of course first i have to get the
random birthtime out of its class and put it in the array:
$this->data['User']['birthtime'] = $this->Age->getBirthtime();
$this->save($this->data);

Something like that, sorry about my pseudo code.
The problem is that the most of my member varables are classes
actually to be able to randomize or do calculations with their values.
