This phenomenon can occur when something is particularly funny or absurd, triggering intense emotions. It's a common experience that highlights the joy and sometimes overwhelming nature of laughter.
It's certainly hard. I have been doing it for 6 years. Blood,sweat,and tears go in to it. Get ready to work hard physically and mentally.
