It makes us happy (as happy as getting money)!
In fact, it makes us happier than buying things for ourselves.
It makes us attractive.
It uplifts everyone around us.
It spreads like wildfire.
It boosts our health and longevity.
It gets us out of a funk.
It's the most natural thing.
It gives us more time.
It's good for the environment.
