Bacteria is not all that bad for you. Here's a new finding to get you to spend some time outdoors.

Could this be a way to get people to go outdoors more often?
"Mycobacterium vaccae is a natural soil bacterium which people likely ingest or breath in when they spend time in nature," says Dorothy Matthews of The Sage Colleges in Troy, New York, who conducted the research with her colleague Susan Jenks.
Researchers fed mice with live M. vaccae and found they were able to navigate their way around a maze faster than when not exposed to the bacteria. The results were however only temporary, which means in order to keep sniffing these bacterias, one has to frequently spend time outdoors.
"This research suggests that M. vaccae may play a role in anxiety and learning in mammals," says Matthews. "It is interesting to speculate that creating learning environments in schools that include time in the outdoors where M. vaccae is present may decrease anxiety and improve the ability to learn new tasks."
