What is it?

This plant is in our living room and it is getting too tall for the window- the top part isn't getting any sun.  I would like to find out what kind of plant it is to figure out if and how I could cut it and if the cuttings would grow or would any trimming kill the plant.

 

I stand nearly '5"9 and the plant is taller.  It is rather hardy, since we have had this plant nearly three years and it is still living... my mother has a black thumb of death when it comes to plants.
