Other technological advances made during the Paleolithic era were clothing and shelter; the adoption of both technologies cannot be dated exactly, but they were a key to humanity's progress. As the Paleolithic era progressed, dwellings became more sophisticated and more elaborate; as early as 380 ka, humans were constructing temporary wood huts.

Now, she lives simply in a little two-bedroom house on a forested ridge and does her writing on a typewriter (she's working on a novel), mirroring the Luddite tradition she once wrote a book about . At night, she wears a shirt woven with silver fibers to reduce her radio frequency exposure, and though her house has electricity, she shuts it off and uses gas lamps whenever possible. During our conversation, her voice would occasionally get cracked and raspy if I got too close with my audio recorder. In the five years since she’s moved to the Radio Quiet Zone, she hasn't left once.
Chaplins last 'silent' film, filled with sound effects, was made when everyone else was making talkies. Charlie turns against modern society, the machine age, (The use of sound in films ?) and progress. Firstly we see him frantically trying to keep up with a production line, tightening bolts. He is selected for an experiment with an automatic feeding machine, but various mishaps leads his boss to believe he has gone mad, and Charlie is sent to a mental hospital... When he gets out, he is mistaken for a communist while waving a red flag, sent to jail, foils a jailbreak, and is let out again. We follow Charlie through many more escapades before the film is out.
