You may have come across people in daily life who have the ability to completely turn off their emotions for a while.
People belonging to the "Vampire Diaries" fandom, know exactly what I'm talking about.
What is this "Humanity Switch"?
Basically, according to Damon, you can flip your humanity on and off as and when you wish to.
Switching it off lets a vampire detach his/her actions from any emotional judgment or guilt. This is the excuse these creatures have for killing ruthlessly and actually consuming a nutritious diet of blood, blood and just blood.
Can we do it?
Upon whether you really want to, whether you have the will to flip it off or whether the situation demands such a thing of you.
You may have seen...
Some people are able to keep a check on their emotions for a certain time and then simply break down once they are ready to.
Of course, this isn't a healthy way of dealing with problems...but then, what is?
Flipping off emotions, even if for a day or two can help detox. Just stop whatever you are doing.
As Sherlock said...
"Personally, I do not have a single spark of humanity."
Technically it isn't possible for humans to flip off their humanity. But it is possible to choose not to feel.
In fact, research has indicated that individuals with extremely high IQs may not have proportionately high EQs (emotional quotient).
Not every person is the same and no event the exact replica of another. So don't worry if nothing else helps you out of a sticky situation.
Sherlock Holmes, Abert Einstein, Tony Stark and other fictional, as well as real life individuals, have been known to be able to simply flip off their emotions. If they can, you can.
But then... always remember to flip it back on, because even Damon agreed that "If you want to be bad, be bad with a purpose otherwise you're not worth forgiving."
