You are using implicit meanings because they didn’t say, “No one over the age of 30 was admitted.” The focus of these kinds of “revivals” is always youth because they are easy to win over, generate huge numbers, and then they drift away.
In WV, people become husbands pretty young. I was one at 20. My wife was 19.
It clearly says it moved to schools.
But, you’ve staked out your position.
