Apparently, a virus found in inland lakes and ponds can make you stupid.

's called ATCV-1 and was initially only known to appear in algae, but now researchers believe the virus may be transferred to humans through DNA.

James Van Etten, William Allington Distinguished Professor of Plant Pathology and a co-director of the Nebraska Center for Virology, says the green algae is 'very common among inland bodies of fresh water such as lakes and ponds.'

This is the first documented instance of the DNA of algae traveling to another biological kingdom.

Scientists conducted a study with 92 participants. Forty tested positive for the virus and they did worse on cognitive and intelligence tests. DNA from the algae could be found in throat swabs from healthy humans.

Symptoms include always checking the wind, hoping it will be windy, going windsurfing in terrible, cold weather in the months of December through March and wasting a lot of money on windsurfing boards and sails.
