According to the science, it really is better to give than receive. Donating a dollar; sharing a kind word or lending someone a hand changes lives, but can also hugely boost your happiness. So we're teaming up with other podcasts from Hidden Brain to Revisionist History to ask you to give to a charity helping some of the poorest people around. We're calling it #PodsFightPoverty.

Go to givedirectly.org/happinesslab right now and give whatever you can. And the first $500,000 we donate will be matched thanks to our friends at Giving Multiplier!

Even a small donation will make you feel good and have a much larger impact on the world than you thought possible. To help inspire you, this special episode examines the science of giving and shares stories of heartwarming and impactful acts of kindness.
