Staring at the computer screen

I had some very intelligent thoughts I wanted to blog about tonight. Honestly, I have a couple of really inspiring blog ideas in my head. However, today I was staring at the computer screen all day. Just one of those days were I was working on a couple of different things and did not blink. My eyes have that "I just want to shut" feeling. Am I the only person that does this, or is everyone else as dumb as I am?
