how old is derek and meredith exactly??

In season 3, Meredith says to her mother (when she´s suddenly lucid) that she was in Европа 5 years назад and in season 5 she says to Sadie that they´re no longer 25 sleeping on their way through Europe, so i drew a conclusion that Mer´s 30 in s3, which means she´s 29 when she starts her internship and 31 in late s5...I think time doesn´t always fit in this show, especially months and that stuff, but no matter...I think that Derek and Addison are the same age because they met at med school and they were both taught by Richard Webber and so on...there could be some months или maybe a year, but no big difference....soooooo, I think that Derek´s 8 years older than Meredith, it could fit. and it´s the difference Ты still can handle ;).
...and Cristina is 28 in early season 2, it was written on the board when she was having a surgery ;).

i think that meredith is about 28 years old... she apparently took time off to travel Европа before going to med school but came back after only a few months to take care of her mother, so i think she started med school a год или so later, putting her at about 28. i also think that derek is the same age as addison, putting him around the 39-40 years old mark.

i think meredith is 30 - 32 as there is 5 или еще год between lexie and her and lexie is 24/25 and i thnik derek is like 38 или 39.
