These might be examples of epigenetic control.

MentallySharp Into Their 90s and Beyond
Somewhere (I need to look it up) I have some research reports about
optimism and gratitude affecting gene expression - people who are very
optimistic, happy, and grateful will live longer and healthier lives.
Frank Forman and I were discussing the value (or lack of it, as Frank
see it) of a religious life, and Steve's gene expression emphasis
suggests one of the values. Since both Christianity and Buddhism
strongly emphasize gratitude as a vital virtue (and I believe Islam, not
as sure), that may account for religious people tending to live longer.
Religions remind one to feel forgiving and grateful. Grateful people are
low in cortisol, high in dhea, stronger immune systems, and so on. So
religion may help healthy gene expression. Of course, Frank, you can
always also be grateful to the big bang et seq. but somehow it doesn't
seem as soul-satisfying. So here is my effort at a hymn for materialists.
A hymn for Frank and Sarah
"We thank thee, dear Darwin, down under our feet,
For all life's developing complexity.
We thank thee for frontal lobes mighty and full,
And right temporal lobes where we feel mystery's pull.
Oh, dear father Hubble, as stars rush away,
We're glad they have given us an earth where we stay.
And for a world tilted just twenty-one degrees,
That makes life adjust to the changes we need.
The Anthropic Principle fills hearts with delight,
As we ponder the chances that life would arrive
From strong and weak forces ideally aligned
To tickle our minds with the presence divine.
Now let's nurture gratitude deep in our hearts,
So good gene expression will sure do its part
To lengthen out full lives for you and for me
To create our very own divinity!
