What's in a name? How does it affect the course, or even the length of your life?
That question drove Michigan State University economist Lisa D. Cook to dig into three million death certificates in four states from 1802 to 1970.
And that led to some intriguing findings, especially about the names of black men.
"We see naming patterns that typically start in the 1960s and the 1970s, and that's written about a lot, but we don't see anything before that," says Cook.
As Cook went through the death certificates, Cook and her colleagues discovered that African-American men with well-known Biblical names or other historically popular names from that era lived significantly longer lives than those who did not have those names.
