  Theoretically, time travel is only possible going forwards in time, not backwards. For arguments sake, let’s say it was possible, and I found myself back in 189 AD. I would try use my scientific knowledge to create things before they were actually invented and become a world famous scientist and scholar like Leonardo da Vinci. Hopefully, since I could take advantage of my knowledge of scientific advances before they were actually made, this would mean technology that was available today would be much more advanced than it actually is.

  I’d try and make it fashionable for women to have body hair too. Shaving legs is really boring and there’s no reason for us to do it. People only expect us to do it because it’s something that’s happened in the past. Think of all the hours across the world that would be saved every day!
