One of the upsides to having a four-year-old computer

I realized about half way through typing a post for Tumblr that I wasn't even looking at my keyboard. Not sure when being able to do that happened but I'm pretty sure I have to look at the keyboard of every other computer when I type. I've just had this one for just over four years so we're really close to each other. I understand that quite a few people can type at any keyboard without looking at it but even though I've been using computers as long as I can remember, that's just not a skill I've ever been able to accomplish.
