ONLY DO THE SCIENTIFIC IF YOU ARE READY TO FACE THE HARD AND SOMETIMES SCARY FACTS Some parts play out by themselves, but you often have to click arrows to go to the next part :D Disclaimer!!! Interactive is only for the "Simplified" versions and still has a lot of reading.
Some information was based off of personal experience and knowledge, but when doing the scientific part of Type 1 and everything of Type 2 I did research. Links are added incase people want to research farther.
