If they were alive today, they'd be in their mid-forties. However, if you look at the age distribution for Iran, you'll notice that 2/3rds of the country is under 25 years of age--and damn near none of it is in the 35-55 demographic.
All the Iranian Islamonuts from that age cohort went off to war, waving Khomeini's Green Book...and died.
The current group of students blame the mullahs for destroying their country and their freedom.
How long until these "students" are chanting "Death to America" in the streets again?
20-25 years would be just about right...
