A while back, I received a phone call from George Rupp.

At the time, Rupp was the president and CEO of the International Rescue Committee (IRC).

Founded by Albert Einstein, the IRC serves refugees and communities victimized by oppression or violent conflict. When thousands run from natural disasters, war or repression, the IRC is there, providing food, water, shelter, healthcare and education.

That year, I had sent my readers a letter reminding them how incredibly rich our lives are and asking them to remember the IRC, the world’s recognized leader in humanitarian emergencies.

I had never heard of George Rupp, however.

“I’m just calling to let you know how much you’ve inspired us – our whole organization – with your letter,” he said.

Embarrassed, I mumbled something in response.

“We’re planning to read it to Tom Brokaw and the other directors at the annual board meeting. We’d also like to turn it into a national fundraising letter. Would that be all right with you?”

All right? I felt like I’d just been injected with 100 milliliters of pure dopamine. I love the IRC. I love sharing its mission.

By the time I got off the phone, my wife said I was acting so goofy I might as well take the rest of the day off. When I walked outside, the sky was bluer, the neighbor’s dog was friendlier and the birds, I’m sure, were singing in counterpoint. It was a weird feeling.

But not unusual, perhaps. Studies have shown that we’re actually hardwired to feel good – and live longer – by helping others.

Dr. Stephen Post, founding director of the Center for Medical Humanities, Compassionate Care and Bioethics at Stony Brook University School of Medicine, says, “The remarkably good news is that, over the past 10 years, we have about 500 serious scientific studies that demonstrate the power of [generosity] to enhance health.”

You’ve always known that giving is its own reward. But science has discovered a slew of side benefits.

Here are just a few recent findings:

Not bad. And there are many ways to give. Money, of course, is how most organizations get things done. But there are effective ways to donate your time as well:

Biologist David Sloan Wilson says…

We have said since millennia – in fact, this has been a fundamental tenet of religion – that if you do good things, it will reflect back to you, not immediately, not every time, but in general. This is a deeply entrenched notion.

Now science is confirming it.

Giving is a simple act. Yet studies show that generous behavior may do more to protect and extend your health than vitamin supplements, green tea, fish oil or an aspirin a day.

Each of us is flawed in a hundred ways. But giving redeems us. It ennobles us. It helps us create a better version of ourselves.

In his book Why Good Things Happen to Good People, Dr. Post writes…

You wish to be happy? Loved? Safe? Secure? You want to turn to others in tough times and count on them? You want the warmth of true connection? You’d like to walk into the world each day knowing that this is a place of benevolence and hope? Then I have one answer: Give. Give daily, in small ways, and you will be happier. Give, and you will be healthier. Give, and you will even live longer.

There are many worthy organizations that would welcome your time and money. To learn more about the fabulous work of the International Rescue Committee, visit rescue.org.

Good investing,
