Using your non dominant hand to do simple chores can improve your mood and your memory;
that's because the action stimulates the production of brain-derived neurotrophic factor(BDFN) a protein that encourages the growth of neurons linked to long-term memory and mood. " When you're depressed or under stress, your brain's producion of BDNF plummets", says Moses Chao, professor of neuro science at New York Universitv School of Mecdine. ( One of the lesser-known effect of antidepressents he says,is to raise the levels of BDNF.) Anything unexpected, smelling rosemary first thing in the morning, for example can activate BDNF.
