why you can still watch the world cup
assuming
that you study in the day from say 0900 - 2000 (inclusive of breaks and what not)
that no matter how much / little you sleep you will still be wide awake in the day
and that you cannot decide whether you shld be watching the world cup or not because common tests are coming,
you shouldnt even bother thinking abt tt qn!
because. world cup starts after 2100, and so when you watch world cup, the opp cost is sleep.
so ur studies, based on the above assumptions, WILL NOT be affected
but. the 2nd assumption is one hell of a big assumption.
of course there are other factors involved. but as long as the 2 assumptions hold true. u can be sure that world cup isnt y u may not do well - assuming of course u din do well. tt's y i used MAY. haha.
in peace. crap logic. i m sorry u jus wasted a minute of ur life reading this.
