Clench your hand to improve memory

StrategyEdward KiledjianComment
A study published in journal PLOS One indicates that clenching your right hand (aka making a fist) may help improve your memory. Later clenching your left hand will help remember that memory.

"The findings suggest that some simple body movements -- by temporarily changing the way the brain functions -- can improve memory," Ruth Propper, researcher, Montclair State University.

Additional research will have to be conducted to determine if this action can help with other functions.
