I'd want to go back to the 1970s and interview the porn stars and directors to find out why an actor needed 10lbs of pubic hair (and 20lbs of body hair for the guys) in order to be in a porn.

Probably not anytime before antibiotics were invented. I'd be hoping to make a return trip. Maybe the late 60s/early 70s

Either late European medieval time, so ~1600 maybe, or when it's just about taking a quick look around then definitely when the first human settlements developed or when the first land creatures roamed earth. Would be hella interesting how the flora would be at that time
