One of the greatest advantages living humans have over the undead is the ability to communicate. One great thing that spawns from this is protoculture -- the ability to teach. In this, the information age, we are able to share our experiences (no matter how arbitrary) with others through a variety of means.
The means of expression could, hypothetically, become scarce during a large-scale outbreak. This would be a great detriment to our chances of survival as a species if we are cut off from communication, a tool we so desperately rely on for survival. There is, however, the unfailing ability of man to document. Even from the dawn of time, man has retold his encounters in cave paintings.
This brings me to my question.
Which format would be more viable as a means of documentation? Writing or video-recording? (We're operating under the assumption that the documenter stays with only one of the two formats, seeing as how few people tend to watch a movie whilst reading a supplementary novel.) Consider the pro's and con's of each. Will you be able to carry a camera safely? Will you always find time to write? Would recharging the battery be viable? How much of a problem is the language-barrier? Would it be easy enough to carry video recording media? Could you keep all of your papers together?
I haven't been here in a while, so forgive me if this is a tired subject.
