my conjecture:
let x be the level of school you are at now(s1, j2, p5 etc)
let y be the weight of your school bag (on average)
x is inversely related to y
last time when i pri sch my bag f***ing heavy. whole day bring so
many textbook
then i sec 1 sec 2 still quite heavy
then upper sec quite light, put all the shit in classroom
now jc even lighter
my father whole day say why your bag so light, go school do
what
lol
