I like being in a factory, and I like working with engineers. I worked as a chemist at a medium scale facility that made industrial strength detergents. They have these huge mixing vats and a network of pipes to carry the various chemicals. You walk up on the mezzanine and it's really slippery, there's wet stuff everywhere and lots of metal, confined spaces, moving parts, places to fall, weird chemicals, etc.

I might have a different opinion of factories if I had to work in there all the time, but my job allowed me to retreat to all different places within the building -- the factory, the warehouse, the labs, the engineers' testing room, my cubicle, etc.
