So I've been watching a lot of videos on speaking and communication recently because I want to be an effective speaker and communicator in everyday life and interaction with other people. I've mostly focused on observing important political figures (Presidents, Senators, Royal Family etc.) and successful business persons (Entrepeneurs, Investors, Successful People etc.). One thing I have noticed about all of them during interviews and speeches is that they all share one common characteristic when they speak. They all take sudden little quick gasps of air at opportune moments. It's almost as if they pause on purpose and then suddenly breathe in quickly and resume with what they were saying. I have noticed that they ALL do this but what is the purpose? What do they pause for? and more importantly why do they always sneak littles gasps of breathe at sudden opportune moments? Can anyone enlighten me as to why this might be? It's just wierd because they do it even when they are not out of breath which indicates its not from lack of oxygen? What are your thoughts on this?
