Splitting one great thing into two doesn't make it two times better. It actually makes the two individual parts half as valuable on their own.
It's like trying to slice a sandwich down the middle. There's not only usually one side that reaps more benefits, but there's inevitably some bread remnants that crumbled off during the cutting process.
Lesson: Don't cut a sandwich in half if you can grip and eat the sandwich with both of your hands all at once. You'll take in more that way.
