Virtual life

Time is expensive, if we think about life expectancy.
There are so many virtual things to do these days with your free time, and it's better to use the time more efficiently. However, there are many "Time Killers" that we need to be aware of; watching TV, Surfing the internet, video games, playing with "stupid" cell phone and more...
I can't really remember special moments when I used to sit for hours in front of the computer or TV. But I do remember good times when I used to take my dog for a walk in the park. Therefore, I feel that the virtual life kills the time, and you only think that you enjoy the moment; however, this time won't even stay in your memory later.
I do think that it's OK to do these things every for a short amount of time. On the other hand, we better be careful and look at the time. We may miss the real life that is passing if front of our eyes. Taking a walk in the nature, spending time with family and friends and more.
Technology is cool, but let's not become the machines...
