A busy attorney regularly works out with the help of a trainer at the local gym. She pays $400 per month directly to the trainer for this service. Over time, the two fell in love and got married. They still work out together (just like before) and she still gives him $400 per month but they both consider the money to be "spending money". Assuming that this is the only thing that changed, what happens to the GDP? Explain and support your answer. (hint: this money is no longer in market activity)
