Smile! It is Good for Body and Brain.

Researcher Ron Gutman (Ron Gutman: The Hidden Power of Smiling) has been studying smiles for 30 years beginning with a study at UC Berkeley. Gutman presents his research in this TED talk and suggests that suppressing a smile can impair judgment while smiling can stimulate the brain, lower stress-inducing hormones, and leave a positive impression on others.

Might it be the case that smiling more might even help one get through the challenges of graduate school? Such challenges include: sitting for long hours while studying in the library, or participating in seminars; reading copious journal articles, often by the glow of an LED screen; practicing the skilled art of negotiation when planning out academic schedules with faculty; listening intently to academic arguments made by your peers.

Often, we think of emphasizing exercise and diet in order to successfully navigate the challenges of graduate school.

Now, how about managing to smile more, too.
