Hmmm there's another one right there. Marital harmony testing centre for new products. Find volunteer couples, cameras in living room and kitchens. Introduce products and then sell with a marital harmony index metric based on AI identified number of minutes per week arguing. Might be on to something here 

 You definitely are.. bookmark this note man, there's a lot to cook here and develop, I strongly believe you are on to something here.. 👀🍀
