As I grow older and as men and women get older I see less and less difference in the male and female genders ...  that leads me to think that maybe most of the differences come from cultural biases.  For example - I used to think that my husband was very different than I am but over the years as we have continued to reveal ourselves to one another the truth is that at the core of ourselves we are very much alike and a lot of what we were "being" for so many years came from what we were taught we should be because of our gender.
