Question 5

did freud invent the term a defense mechanism?

Accepted Answer

Interesting?: The etymology of the word defense dates from around 1300 ce from what i can tell.  Defense mechanism plays an important role in freudian psyhoanalytic teachings and dates from about 1913.  It has been parlayed into many other roles that have nothing to do with id, ego etc, but I do believe freud deserves most of the credit for our modern use of the term.

Question 6

for what reasons was the bmi calculator even invented?

Accepted Answer

For studies: In order to study obesity, one has to have a definition of what it means to be obese.  You can't simply use weight, as 200 lb might be obese for some people but would be a thin person if their height was 6 ft 8 in.  Bmi takes into account height and weight.  A bmi over 30 is considered obese.
