WHY?

And for what do you live? There are many changes in our lifes.. New people, new places, new situations.. We're working all week, then spending weekends near computers or TV.. What is the sense of all that? Do you like that way you are living? If no, may be it's not too late to change something? We don't know how many more days we have to spend here..
It is strange how things can turn around and how fragile is life . Why so bright personalities go in such young age?
