Do we live in a pedocracy?

Im not a scientist. Quite the opposite. The question is
>why has no one measured death?
That might sound like a funny question, what do you mean "measure death?" Well, there are many different ways to measure something, or record activity. This could be electromagnetic activity, infrared activity, all different types of physical activity that we can't sense with our organs. There is no case of people recording and measuring deaths this way to compare and contrast similarities and differences. How can we have any idea what happens after death if we dont study it?
