In a relationship when things are really great you don't need to say anything and just enjoy the other person. Sometimes with a couple it gets dark and you don't know what to say and that silence can last all day. Other times you don't want to stop talking because you don't want to lose one another.
Certainly going back to Sherlock Holmes we have a tradition of forensic science featured in detective stories.
In the forensic science course I took at university they used photographs of dead bodies. For ballistics they showed us a guy lying on the floor and his head had burst.
I didn't invent forensic science and medicine. I just was one of the first people to recognize how interesting it is.
