What you do in front of a comp??

I was wondering why people like to staring with the laptop all the long...
One of the people is me...I don't know why...
It just like a daily task for me...
Once I woke up, then I have to open my comp and check mail, login to friendster, login to facebook, login to msn....blah blah blah....
I'm wondering why I would put all of these in my daily task..
I also tried to ask some teenager that could they live without internet..
In fact, the answer i get from then is can't...
Is Internet that important to all the people??Is computer must be use everyday??
Is it a must??
I'm just wondering...
