unless of course i disguised myself a s a giant rabbit from the future. but then I'd be too scared AND theres still the issue of the paradox.
if i had to live in the past, although almost any point in any civilisation would be cool, esp my beloved Roman ancestors, I'd hate to live at any time when they didnt have antibiotics. Even though I'm allergic to them now mind you, can you take your knowledge back in this thread-idea? Or is it just which times in the past you admire and would feel comfortable in.
if the latter, then the Sengoku period in Japan.
