Game of Thrones, again: the actors ages

I have been wondering about this for ages: everyone in the series looks so much older than I have imagined them to be, practically everyone. It bothers me in few cases , especially with Cersei who is supposed to be this undenied beauty of her kingdom, but as much as I think Lena H. is a gorgeous woman, she is not beautiful enough. I am also not happy that The Hound is so much older (although I like how Rory McCann plays him), but I fear The Hound's story is not going to be quite the same as in the books anyways.

There was a very interesting post in Russian "Game of Thrones" community, here, by serebrenikoff.I added Bran's age myself.

In tangential note, whilst looking for GoT communities (as obsessed person I am), I also found French, Italian and Spanish GoT communities on Lj , which is awesome.

Here is the translated age table (please let me know if anything is not correct):

Character	book age	TV age	Actor age
Eddard Stark	35	40	52
Catelyn Stark	34	35	39
Robb Stark	14	17	25
Jon Snow	14	17	25
Sansa Stark	11	13	13
Arya Stark	9	11	11
Bran Stark	7	10	11(?)
Robert Baratheon	36	40	47
Joffrey Baratheon	13	13	18
Tyrion Lannister	24	30	40
Jaime Lannister	32	35	40
Cersei Lannister	32	35	37
Sandor Clegane	27 (?)		42
Theon Greyjoy	19	19	24
Viserys Targaryen	23	20	27
Daenerys Targaryen	13	15	22
Jorah Mormont	40	40	49

I wonder if it is just me or if the fact that so many characters are older bothers anyone else?

Also, some of the characters are not in the list, please let me know if you know the ages in the book and TV for:

Petyr Baelish
Lysa Arryn
Barristan Selmy
Renly Baratheon
Loras
