I do not use my mobile phone while doing any work. Because I know that using a mobile phone reduces the efficiency of the work. A person who works with me in the office is glued to his mobile phone even while on duty, and the company does not benefit from him. This is how the mobile phone was the reason why he did not get a job promotion and I got a promotion. If you use a mobile phone while driving, you can completely lose focus and even risk your life.
