The science of love. Very complicated.
Biology of course!
Strangely enough I do not answer too many biology questions here.
Anatomy and physiology.
Does no science count? Hahaha
Space. My father worked at NASA - it's the unknown
Archaeology. I love seeing old mummies, artifacts, pottery and other ancient or medieval relics.
Physics but you can tell by my degree what my actual science love is and for many who don't know what Social-Psychology is , its actually street Pyschology as pertaining to Law Enforcement, a little like Profiling but more advanced and differs from regular Psychology as I don't use a room.
