There are people who in their free time stay slouched in front of their televisions and stare into nothingness(literally). Some find excuses to not stir a limb, I bet they gather moss after a while.
But then there are people - Experts who can take the art of lazying around to new levels - These poeple are students.
An unaccustomed eye would not be able to tell a lazying student from the one who is actually studying. They will always appear engrossed in work - any kind of work. Wont be free at any time of the day.
And yet, at the end of the day the net output will be zero.
And yes, some choose to spend their times blogging.
