Mo Islam asked the Naked Scientists:































































































































   People have different types of laugh, from insistent giggling to, bout of laughs, to tehehehe; everyone seems to have a different types of laughs.  The question is do this different types of laugh gets established for a person through nature or nurture?  Could a person change the way he/she laughs if practice hard enough?  Or is it completely uncontrollable?































































































































What do you think?

Humans are pretty resourceful and quick learners. In the same way that we can train to speak a certain way and hone or adjust an accent, I suspect that laughs are similar.
