In the U.S. and Canada, 50% of the young leadership of all the organizations like AIPAC and Hillel are Birthright alumni.

Over 90% of participants are satisfied with the Birthright experience.

In my 40s - when I was giving to the Red Cross, United Jewish Appeal and other charities - I said to myself, this is all well and good, but these are really amorphous things, and maybe there are some causes out there that I really give a damn about.

Across all religions in the United States, people 18-30 are more spiritual than before, but they don't like organized religion. What sets Birthright apart is that no one's hitting on you to be Jewish in any particular way, and you can define Jewish any way you want.

I didn't realize I was working in a family medium.

My family always encouraged my drawing ability. Kids in school who teased me about my reading would get out of their seats and stand behind my desk as I worked and go, 'Wow, you can really draw.' Later, I earned a degree in Fine Art and got a Ph.D. in Art History.

In my child's-eye view, whenever I was exposed to pain, it meant that my mother had let me down.

Charles Darwin and I and you broke off from the family tree from chimpanzees about five million years ago. They're still our closest genetic kin. We share 98.8 percent of the genes. We share more genes with them than zebras do with horses. And we're also their closest cousin. They have more genetic relation to us than to gorillas.
