If it is simply a state you want to save then you do not have to add anything in Blender. It is just Python and SDL. The SDL file for an on/off state would look something like this. 

STATEDESC MyAge
{
   VERSION 1 
   VAR BOOL    MyState[1]   DEFAULT=0
}

DEFAULT=0 will set the variable to 0 when the age is visited for the first time. Note: "MyAge" should be changed to match the name of your age. Also, the SDL file should be named MyAge.sdl and placed in the SDL folder.

Reading an SDL with Python: 

           ageSDL = PtGetAgeSDL()
           getSDL = ageSDL['MyState'][0]

Changing an SDL with Python: 

           ageSDL = PtGetAgeSDL()
           ageSDL['MyState'] = (1,)


To allow your Python object (or plModifier) to be notified upon any changes in the SDL, you'll need to first initialize the SDL variable within the OnServerInitComplete() method: 

           sdl = PtGetAgeSDL()
           sdl.setFlags('MyState', 1, 1)
           sdl.sendToClients('MyState')
           sdl.setNotify(self.key, 'MyState', 0.0)

Then the plModifier's OnSDLNotify() method will be triggered when the variable changes. Here's some sample code to detect a change: 

   def OnSDLNotify(self, VARname, SDLname, playerID, tag):
       if (SDLname != "MyAge"):
           print 'SDLname =',SDLname,', not MyAge'
           pass
       elif (VARname == "MyState"):
           ageSDL = PtGetAgeSDL()
           getSDL = ageSDL[VARname][0]
