Hello Sara:
Truth for one thing. Teaching English as a second language for another.
The study of Mathematics and teaching it also.
I am also passionate about reviewing books. (I have over 300 book reviews on Amazon.com.)
Generally however, my interests are Science, Philosophy, Theology and Law.
My additional interests are Fine Arts, History, my 50 gallon aquarium, and the study of Electronics.
What about your interests Sarah?
