Umm... if you are over 40 in Iran than you are either the Shah or a foreign diplomat https://www.cia.gov/library/publications/the-world-factbook/...

Median age doesn't say much about the number of people over 40. Life expectancy in iran is around 70 [1].

Also, the last shah was overthrown in 1979.
