Complex systems science.

I think I've found what I want to do with my life. Complex systems science. There are a number of reasons I'd like to do this, but primarily because it is a vast and increasing science.
Complexity is everywhere around us, from the pattern of tree growth, to human interaction, to the stock market. Complexity is everywhere. And there are so many 'rules' that complexity appears to adhere to. I've always thought, 'what makes a cell KNOW to kill that other cell', and complexity science is what is finding those answers and, more importantly, finding new questions to ask!

So many of the areas I'm interested in have complex roots and would be a great stepping stone to complexity research. Computers, linguistics, brain science, cellular science, psychology, politics, and more! I've never felt 'called' to do something until now...
