Research of the inconclusive mind

RESEARCH TOPICS! well theres a few that pop into my mind.
one topic i would love to dive into would be the history and art of piercings. always been a fan of piercings but my job never let me get any. oh well i figure something out right? but i would like to know where piercings got there start, like what culture used it the most, when did it become popular in the united states, and how are modern day piercings done as opposed to primitive cultures piercings. Another facinating topic i would research would probly be the origins or electronica, or techno. all i really know about it is that Kraftwork was one of the first groups to first put it out there. Id probly find out, who the first electronica artist(s) were. where the scene first started to develop and how has it influenced the music of today. I beleive these questions would be very interesting and have a lot of entertaining material behind them.
