If one was to watch a film that had no colour or sound, it is not going to be the same as a film that has colour and sound. It is unlikely to be as engaging or as entertaining, and one might soon lose interest and turn it off or walk away from what they’re watching.
And the same could be said about the impact that feelings have on one’s life. If one was unable to feel, their life would feel empty and without meaning. Through having the ability to feel, life is brought to life and given meaning.
