Top 5 Ways to Get Smarter

Ingest Bacteria

In June 2010, researchers at The Sage Colleges presented findings that show certain types of bacteria commonly found in dirt made mice "smarter." The mice given Mycobacterium vaccae performed better in maze tests and showed fewer signs of anxiety and higher levels of serotonin in the forebrain, the area that takes care of higher-order thinking. The bacteria seem to promote the growth of neurons as well. This doesn't mean that we should all go out and start shoveling dirt in our mouths: You can actually ingest it by doing yard work, gardening and even by simply taking a walk through the woods.
