At the computer

I'm at the computer now sitting here in my room. Looking at the screen and wondering how many times do I sit here a day. Wow! Its nearly very depressing. But No, I do more things at the computer desk then just search the web. I write all my creative ideas down,and I type my manuscripts. But I wonder how many times a day do we just waste away at the computer. Sure we can be productive at times. But the other half of the time what are we doing? So I was thinking what are ways we can limit our "At the computer" time? I know for sure I don't want to limit it to much then I wouldn't be able to keep up with the blog.So give me your ideas? Can't wait to hear from you.
