Once one of our teachers at the university said,
"we are not studying something that will happen after death. What you are studying, you can relate that."
If you study in management, probably you have courses like Business Communication. Communication is so important not only in business but also in personal life as well as self-defense. You can react fast and make your move observing the attacker's nonverbal communication even if he lies.
Thank you so much @tariqul.bibm for your feedback!
