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 Person ( name varchar(20), age INTEGER, city TEXT, gender TEXT, job TEXT )
TABLE: CREATE TABLE PersonFriend ( name varchar(20), friend varchar(20), year INTEGER )

### Question ###
Who has friends that are older than the average age? Print their friends and their ages as well using a bar chart, and could you show by the friend in descending?

### Accurate SQL ###

SELECT friend, age FROM Person AS T1 JOIN PersonFriend AS T2 ON T1.name = T2.friend WHERE T1.age > (SELECT AVG(age) FROM Person) ORDER BY friend DESC
