    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT T2.Description FROM Series AS T1 INNER JOIN SeriesNotes AS T2 ON T1.SeriesCode = T2.Seriescode WHERE T1.SeriesCode = 'SP.DYN.TO65.MA.ZS' AND T1.Topic = 'Health: Mortality' AND T2.Year = 'YR1967'
