3 Billion.

That's the number of hours, on average, contributed by Americans aged 55 and older in service between 2008 and 2010. Some of these individuals serve with Senior Corps programs like RSVP while others may give back through local faith-based or community organizations, but all provide valuable human capital which communities in need are able to depend on.

Today, President Obama declared May Older Americans Month and next week, May 7-11, the Corporation for National and Community Service will celebrate Senior Corps Week. Both of these events provide an opportunity for citizens to reflect on the positive impact that older Americans have in communities throughout the country.

With all this excitement around older Americans, we wanted to share a few of favorite excerpts from today's proclamation:

America endured great trials and heralded defining triumphs over the course of the 20th century, and the men and women who saw us through that time remain among our Nation's greatest assets. Through their guiding wisdom, enduring love of family, and inspiring commitment to country, older Americans continue to steer and enhance our national life.

Our seniors make countless contributions as active participants in communities across America. From our parks and schools to our faith and service organizations, the generosity and talents of active seniors augment our children's education, bring our families together, and strengthen the fabric of our society. This year's theme for Older Americans Month, "Never Too Old to Play," celebrates the accomplishments of older Americans and encourages them to find even more ways to stay engaged. May 7 through May 11, 2012, is also Senior Corps Week, when we celebrate the service of the over 300,000 Senior Corps volunteers.
