Just yesterday, I was thinking about the meaning of love and thinking...Why do humans need a mate?

I spent about 30 minutes searching the internet yesterday trying to find research that would explain it.  After reading 4 or 5 stories on the subject, I realized quickly that I was just wasting my time.

Ironically, out of the blue, a friend of mine sent this to me today and it may just shed light on the reason, as humans, we are in constant search of love.
