 Day number three, $5. And they did that for a few days. And every time they asked the people, well, how much did you enjoy whatever you got with those $5? In another condition, they gave people again $5, but this time they said, buy something for someone else. So this time you're buying coffee for your colleague or you're buying a pen for your child, right? And every day they give them $5 and they would buy something for someone else. And they asked them, how much did you enjoy this? How much, you know, how good did it make you feel? Now, what's interesting in this study is they looked at the rates.
