    A classic property of this type is height (say in women), which was found to be normally distributed in some of the first studies in statistics. The explanation is that there are many factors which influence height. And there is a theorem that the mean of a sufficiently large number of "variables" is normally distributed---even if the individual variables are not normally distributed. http://en.wikipedia.org/wiki/Central_limit_theorem HTH
