This thought experiment isn't so much about going into the past and staying there to be bored, but going into the past for the (in science fiction) forbidden purpose of personal gain and getting away with it, which I maintain is absolutely possible if you're a bit more creative than "Hyuk, I'm gonna buy me a lottery ticket" and even ethical as long as you don't change history itself, but restrict yourself to your own history. Once you make your changes, you return to the present and reap the benefit.

The secondary objective was to decide who I'd send back if I could, which has been done.

This thread's tertiary objective was to get more pages than the freaking arse hair thread. Mission accomplished!
