Google can explain what an atlatl is, but I had to take some type of sociology or anthoropology or something or other class in college and the only thing I remember from that class was the atlatl! I saw some guy on TV not too long ago trying one out. Didn't seem too effective, but of course, his family's survival didn't depend on his skill level.
Best of luck on your move and new job. The transition is always tough, but it will be worth it looking back in 6 months or so.
