More use than my treadmill has seen in its lifetime.
Using A Treadmill To See How Far Different Pencils Will Write

Because these things are important, this is a video of Youtuber President Chay using long strips of paper wrapped around a treadmill to see how far three different pencils (a cheap #2, an expensive #2, and a Bic mechanical #2), and a pen (Bic red ink) will write, to determine which is the best value. Granted the experiment isn’t conducted in the most scientific way possible and we have no way of knowing if he was using consistent pressure for each pencil, etc, etc, but whatever, the results may still surprise you. Unless you thought the cheap #2 was going to win, because it does. So, the next time you’re looking to save a solid two dollars a year on pencils, go with the cheap ones.

Keep going for the video while I try to remember the last time I even used a pencil for writing and not just a pencil fight.
