How crazy are the folks at Fox News? Very.
Recently on Fox News' morning show, "Fox and Friends", the hosts were discussing research done in Finland and Sweden that suggests that people who stay married are less likely to suffer from Alzheimer's disease. I would suggest, off-hand, that this might be because people showing early signs of Alzheimer's are more likely to get a divorce or have one forced on them, but I haven't read the study.
Anyway, host Brian Kilmeade questioned the results, saying, "We are -- we keep marrying other species and other ethnics and other... See, the problem is the Swedes have pure genes. Because they marry other Swedes .... Finns marry other Finns, so they have a pure society."
