How powerful is the human mind?

[perkeyone]

hmm thats not really helpfull considering you can put more or less info on each page by simply writing bigger or smaller or if the pages of the text book are different sizes (unless there is a standard size for text books) or even by using simpler or more complex sentences that use clauses.
ex. the dog is red. the dog ran. the dog belongs to joe.
vs. joe's red dog ran.
you could get a lot more info on pages if you make the sentences more complex so how do they define the amount of info per page?
