ECO2013 MOD 9 Discussion

I’m working on a macro economics discussion question and need an explanation and answer to help me learn.

First, recall the definition of GDP and how goods and services have to fit the multiple aspects (shown in bold below) of that definition in order to be included in GDP:

GDP represents the market value of final goods and services produced in a country in a given period of time. 

For your main post, give an example of a specific good or service that is currently NOT included in GDP but that you think represents substantial economic activity and should therefore be counted in our GDP. Explain what would have to change, using the definition above, in order for that good/service to be included in GDP.
