My personal favorite science. I have dearly loved it since I was young, and my only true regret might be that I didn't pursue it to a higher degree. But I had a terrible first teacher in college as a followup to one of the most amazing teachers on the planet in highschool. Also I was busy with...other things in college.
Plus i'm a grownup now, I have enough money to live, and I can do more or less whatever chemistry I want. Assuming I can convince my wife it will be safe to perform around the children.
