I am a factory worker and have been for a while. You know a factory or manufacturing plant on an industrial site.
What kind of products do you make?
All sorts, I just do the heavy lifting. Since working there I have become curious about how factories arose with the introduction of machinery during the industrial revolution. 
How long have they been around?
Well the industrial revolution was the transformation and transition into new manufacturing methods from around the 1760's to 1840's
That's interesting. What types of machinery do they use these days?
Well todays manufacturing is more space aged in comparison to the past as we use robots and computers to be precise with the manufacturing methods taking out human errors. 
Wow, that's great. Can't be too careful
