Many students caryy briefcases that are too heavy.
The average weight of a backpack of Belgian students is 15% of their body weight. That is alot more than the norm of 10%; this scientific norm declares that a backpack may weigh maximum 3kg for a person weighing 30kg.
If you exceed the norm of 10% then the position of your back starts deviating from its optimal position and you start to walk differently. As a result you will be tired much quicker en you can start to develop backpain, now or at a later age.
About 60-80% of the adult people have backpains. They are of course not all caused by carrying a heavy backpack but it is in everybody's interest (and the societiy's) to get that percentage down.
