Too old to work (or change your job!)

At what age do you settle down and just get to the stage of finishing off your working life by just 'gliding' through your current job ?. in my case it seems - Never !.
At the moment i am working for 2 very good companies one for 3 days per week , the other for 2 days per week. Lucky you - you might say , and to a large degree i would agree. However i have just seen a job advertised that just gives you that ' i would love to do that' feeling. - so i have applied for it. It is still IT related but the added bonus is that it is dealing predominatly with Photoshop, maintaining and restoring a photography collection. Now how cool would that be ???
i am sure that there will be lots of others applying but i am confident that my experience will see me through. you can see the examples i have created at www.peterelliott.info/photo.htm. Opinions welcome

will let you all know how i get on

Thanks for reading
