I haven't always wondered this I only started wondering it the other day and since then have wondered some more. As babies we learn to talk and speak quite often by mimicking. We have similar accents depending which part of the world we are from but what defines our laugh? Where does the sound of that come from? Is it a conscious decision at such a young age to decide what our laugh will sound like, remembering that laughter just happens it is something you do. I didn't pick the sound of my laugh, i just had it it was one of the first things i did, there are so many different laughs in the world some are way funnier than others. Some sound weird, some are hearty, some are shrill, some sound freaky, why do laughs sound like they do? why do we get the one we are given?Where did it come from?
