history: When i worked as a machinist, i was the only person on my shift that could program a certain lathe that had 6 axis. It was when i was at the top of my abillitys. Have you ever rode on a roller coaster? Yes when I was young I did all the time_comma_ but I think after I turned 18 I got this weird fear of being so high up in the air. What about you?
current: I hate riding them, but i used to machine components for their drive chain when I was a machinist.
next: Wow thats really cool! You must be happy to know about that stuff its interesting!
