It was tiring to the brain and body. My eyes were strained and my left arm almost got numb many times after placing it on the arm rest when I was too engrossed. Thousands and thousands of switching tabs, at least they proved that I could work faster by using this method.
Perhaps, only people who are doing the job could feel the pain; the rest would just jeer, “Hey why are you taking your own sweet time? Are you having honeymoon?”
I hate owing people work.
