My research was based on Flies. All i did for 3 years was to watch those  flies mate and see how many males and females they give birth. Count those flies, watch them have sex and all that bullshit. 
That's why i am saying it was a waste of time, at least for me.

At the end what did i learn ? Nothing. I knew about flies having sex when i was a Kid. In fact i knew more when i was a kid. I could tell whether it was a male or female just by looking at it.
