Does anybody knows how old Dean was when Adam was burn?

uhm lets see... Sam zei that Adam was born in september 1990 that makes Adam 19 now and Dean was born in january, 24, 1979 which means that Dean was about 11 years old when Adam was born and Sam 7 i think

im not sure but im pretty sure he was 11 coz he is thirty now.

Dean is born 1979 and Adam is born 1990 so he was 11.
