For decades, tabloids and talk shows have fed the belief that one in three children may be illegitimate. It's a shocking number, one that we put to the test, thanks to modern science and one historic survey. Witness the surprising findings as we conduct the world's first specially designed paternity poll, and follow three people who put fatherhood to the test to find peace.

Our hands have stories to tell, but can they actually inform us about our health, our personality, or how long we may live?

Then witness the surprising discoveries made when modern science puts breast tissue and breast milk under the microscope.
