In the 70's movie Logan's Run, I'm confused about how people age.
The opening scene to the movie shows Logan 5 at a nursery where he is curious about his first born son named Logan 6. So this indicates that people are born naturally from woman, and start life as babies. At the time of their birth they have their "life-clock" installed in their hand.
This is the only time young people are shown inside the sealed city (with exception to the feral children).
Later on, when Logan 5 first meets Jessica (by way of teleporting her to his apartment). They have a discussion about the ethics of killing by the sandman, where Logan pulls out a gun and asks her if she is thinking of running. She replies with something like this "I'm only 6 and won't even turn green for another year". I can't remember the line exactly, but I don't understand how she could be only 6 years old?
Later, when Logan and Jessica chase a runner into an abandoned part of the city where there are feral children. Logan explains to one of the youths that he (the child) will soon turn 16, and that children who turn 16 are killed by the other children.
So I'm confused as to what Jessica meant when she said she was only 6, and why the feral children appeared to be aging normally while everyone in the city were adults.
