Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE church ( Church_ID int, Name text, Organized_by text, Open_Date int, Continuation_of text )
TABLE: CREATE TABLE wedding ( Church_ID int, Male_ID int, Female_ID int, Year int )
TABLE: CREATE TABLE people ( People_ID int, Name text, Country text, Is_Male text, Age int )

### Question ###
Show the name and age for all male people who don't have a wedding. Visualize by pie chart.

### Accurate SQL ###

SELECT Name, Age FROM people WHERE Is_Male = 'T' AND NOT People_ID IN (SELECT Male_ID FROM wedding)
