Be profligate to propagate
Go decorate and waste,
Entice, delight and entertain
With zeal, make your case.
Sing, laugh and dance
The night away, in joy of lushness share
Exuberant displays the way
To win creations ware.
A partner for the dance
Of life will watch you and will know
The vigorous display of yours
Must be a costly show.
And cost is good
Revealing all for everyone to see
A fitness such to leave
you well, with excess energy.
So they will know that your genes are,
with few mutations, fit
By your display of uselessness
Like poetry and wit.
Sometimes I think,
she says with a wink,
I’m stupid and old
if the truth be told.
Cuz it’s hard to remember
the last time I was young,
she says cheek in tongue
Now, I’m no mollusk but I do know that as I’ve aged I’ve slowed down . . . along with my metabolism. Turns out this is GOOD news:
Less Active Species May Live Longer
“This is what a group of researchers from the University of Kansas found after taking a close look at some extinct as well as living species . . . analyzing the physiology and evolution of as many as 299 species of aquatic mollusks — including present-day snails and slugs — over last five million years.”
“They delved into the occurrences and extinction of different species over the said period as well as their respective metabolic rates or the amount of energy each of the creature in question needed for survival.”
“Much to everyone’s surprise, the findings of the work revealed that metabolic rates make a reliable factor for predicting the likelihood of extinction of a certain animal species or community of species.”
“We found a difference for mollusk species that have gone extinct over the past 5 million years and ones that are still around today. Those that have gone extinct tend to have higher metabolic rates than those that are still living . . . those that have lower energy maintenance requirements seem more likely to survive than those organisms with higher metabolic rates.”*
“Maybe in the long-term the best evolutionary strategy for animals is to be lassitudinous and sluggish — the lower the metabolic rate, the more likely the species you belong to will survive . . . Instead of ‘survival of the fittest,’ maybe a better metaphor for the history of life is ‘survival of the laziest’ or at least ‘survival of the sluggish.'”**
I was going to go for a brisk walk but I’ll take a nap instead and . . .
live to walk another day.

One of my long time friends (whose initials are jw but shall remain nameless) is a bit of a sugarcarboholic and green isn’t her favorite food color. She also is in chronic pain and lacks energy. When I found this research I wanted to share it and I know she reads this blog.
The Chemistry of Joy
Our mood, outlook and energy levels are determined to a huge extent by the chemicals serotonin, dopamine, norepinephrine and their relationship to one another.
We feel good when they are in balance. Beta endorphins also create a feeling of well-being, connectedness to others, and emotional stability. They even help us tolerate pain.
- If levels of norepinephrine and dopamine are low, people will slow down, sleep a lot, have trouble concentrating and find it hard to motivate themselves. They can have a “sluggish” depression.
- On the other hand, people with high levels of norepinephrine and dopamine, and possibly low levels of serotonin often feel angry, resentful and despairing. They can be critical and demanding. This would be an “agitated ” depression.
- A third kind of depression can occur with low levels of serotonin, which results in people feeling fearful , worried and inadequate. This is an “anxious” depression.
In the Kitchen by Peggy
- Sluggish Depression – Eating to INCREASE norepinephrine and dopamine:
Eat high quality proteins throughout the day, lean beef, low-fat meats and fish.
- Agitated Depression – Eating to DECREASE norepinephrine and dopamine:
eat the same as to increase serotonin but eat very small amounts of protein. A vegetarian diet would be good.
- Anxious Depression – Eating to INCREASE serotonin:
Increase carbs, eat tryptophan, which is in nuts, dairy, and meats. Eat regularly throughout the day. Get some protein, but not a large amount.
