Age Extraction for MIMIC-III Subjects in MIMIC-III Clinical Database

[Zjamil4-c]

Hello I am working on MIMIC-III Clinical Database and MIMIC-III waveform match subset. I would like to know about age of subjects in the MIMIC-III Clinical Database. I understand that the age of subjects>89 years is marked as 300. However, I need to extract the age of other subjects as 58, 21 years, Can you tell me how can I get that from the database?
