I failed to understand "More years ago than either of us would like to say"

Would you like to rewrite it for me?
Thank you.

Attorney General Eric Holder Speaks at the Harvard School of Public Health Event
Boston ~ Friday, May 6, 2011Thank you, Dean [Julio] Frenk. It’s a pleasure to be here. And it’s a privilege to join with so many leaders and distinguished members of the Harvard community. I especially want to thank Associate Dean [Jay] Winsten for moderating our discussion and, more importantly, for his leadership and friendship. More years ago than either of us would like to say, when I served as Washington, D.C.’s United States Attorney during one of the city’s most dangerous eras, Jay and I worked together on several initiatives to reduce youth violence and promote youth mentoring. Today, Jay – and several other members of the Harvard faculty, including Dr. Felton Earls, who I’m glad to see here – are valued partners of the Department of Justice. And all of us will benefit from the perspective and expertise that they bring to today’s discussion.
