Feeling a bit brain dead after a week in the office? Then it’s time for a trip outdoors to ingest some bacteria!

According to research recently presented at the 110th General Meeting of the American Society for Microbiology, exposure of mice to Mycobacterium vaccae, a soil bacteria commonly ingested outdoors, stimulated neuron growth and improved their ability to navigate mazes.

Pity that it’s raining outside right now.
