Hello Maxmoe.

On this Message Hub, seven years ago, Chauncey Gardiner quoted "Business Week" research, which stated (in part), "Dr. Smith earned a BSc in Geology from McGill University in 1959, as well as an MSc in 1962 and PhD in Geology in 1966 from Northwestern University."

Sheila Curran, who is a "Higher Education Consultant," states that "Based on our study of 946 private colleges, if you start college aged 18, you only have a 43% chance of graduating from that school in 4 years, so by aged 22. You have a 56% chance of graduating by age 24."

According to the averages, there's a 43% chance that Smith is 82 years old. Remarkably, there's a 13% chance he is a year or two older than that. There's a 44% chance of graduating beyond the age of 24 or (I suppose by the wording) not graduating at all. In any event, it's 60 years past the year 1959 graduating year.

So if you start at 18 and graduate in four years that equals 82 years old (43% chance).
If it took you five or six years that equals 83 or 84 years old (13% chance).
The remaining 44% are dropouts or seven year plus graduates (now older than 84).
