Juvenile onset MS can probably be accounted for fairly easily by talking to any juvenile about their actual experiences of school and family. There is an INCREDIBLE pressure on young people to perform well at school. They don't even know what they want for their future yet, usually, but they know that if they fail they'll never have a chance to have a good one. The homework is getting ridiculously high, and playtime keeps disappearing into "win or lose" structured "play" organized by adults. Add the nutritional deficit of modern food into the equation...

Sometimes kids aren't allowed or able to be kids. It's no wonder they're stressed out.
