SELECT AVG(LifeExpectancy) FROM country WHERE NOT Name IN (SELECT T1.Name FROM country AS T1 JOIN countrylanguage AS T2 ON T1.Code = T2.CountryCode WHERE T2.Language = "English" AND T2.IsOfficial = "T")

CREATE TABLE countrylanguage (CountryCode VARCHAR, Language VARCHAR, IsOfficial VARCHAR); CREATE TABLE country (LifeExpectancy INTEGER, Name VARCHAR); CREATE TABLE country (Name VARCHAR, Code VARCHAR)
