‘Pie hole’, colloquial for one’s mouth, is believed to have evolved in the USA in the 1980s from the British expression ‘cake hole’ (coined in the mid 20th century). Pie hole refers to a mouth, as in: Shut your pie hole or, in this case: Put less in your pie hole.

Don't Forget to Exercise

You already know there are a multitude of benefits to exercising. You may not know quite the extent and reach of these benefits. Wait for it... Well, maybe run for it...

Several new studies investigated physical activity and it's relationship to cognition. As we get older, we tend to have more "senior moments" or "tip-of-the-tongue" moments where we can't quite remember something but we know we know it. Instead of flopping your fingers over the keyboard typing into Google, it's time to get those flabby arms 'a flapping!
One study found that healthy older adults have more of these "senior moments" compared with young adults. This may also happen to new mothers... Been there.
But seriously, here's a brief overview of several recent studies showing your brain's health is linked to exercise:
  • One study found physical activity intensity was associated with improved performance on several cognitive assessment tasks
  • Another study found that higher aerobic fitness levels decreased the probability of "senior moments" in healthy older adults
    • This study further demonstrated a link between aerobic fitness and language functioning in older adults
    • Perhaps a fit older person could write me a funny joke about hemorrhoids and steroids?
  • A study investigating adults with mild cognitive impairment found subjects receiving cognitive exercises, physical exercises, and music therapy had significantly improved levels of cognition compared to the control group (no intervention) whose cognitive status significantly worsened
    • Yes, that means the exercise/intervention group's mild cognitive impairment improved, while the no-exercise group's got worse
  • Another study found the duration of exercise (>1 hour/day) increased cortical thickness in various areas of the brain 
    • Thinning of these areas is associated with age-related deterioration and Alzheimer's Disease
    • Interestingly, frequency and intensity were not associated significantly with cortical thickness (in this study)
    • The study also found a benefit to education level preventing cortical thinning
Since we're talking about brains. I wanted to pour a little nutrition into this piece too: an article released this week found eating a higher quality diet (you know, one that includes lots of fruits, veg, fish, nuts, whole grains, dairy, and limits sugary drinks) correlated to larger brain volume than those who ate poorer quality diets. Also noteworthy is that our brain volume declines with age, so high quality diets may help slow this process, keeping our brain younger.

What did we learn?
  1. Don't forget to exercise (get it?)
  2. Exercise and a high quality diet can help keep our brains from expiring prematurely 
  3. This research adds to the existing (aged) body of evidence (see what I did there?) that brain health is tied to external factors like diet and physical activity
Here's a good place to get started if you're looking to get more physically active.
