I have been trying to weigh to benifits of intelligence vs. free-rad
production.
I suppose being stupid would kill me sooner.
Someday I'll ask someone to convince me exercise is good
and they will not only list what it does
they will say how it does it,
Aw who am I kidding.

We have STMs and unknown nutrients.
What are they... piconutrients?

How rapidly could I change red/white cell counts?
If it is controlable enough I could:
A)increase plasma during feeding.
B)increase red cell during exercise.
C)increase white cell during cleansing.

:-)
As my pride is wounded from my apparent lack of physiological knowledge,
I will defend myself with my grasp of physics
which extends beyond my body into the hot, dry air
which fills my lungs at the center of my being,
warming my soul by reaching through it's bloody tendrils
(rather much like a central heating system).:-)
I am sorry.
Alas, I could not resist.

In case you missed my point I will try to explain.
Heat is not soley within the cells.
It can be created in them
though I was meerly pointing out that dehydrated toes get froze.
As water being rapidly pumped through the system
disperses warm blood amongst cold blood
the mean temperature is more easily kept regular(regulated).
I feel better now.

Well, I don't plan to use a hyperbaric chamber

That's what I want.
A machine that replentishes the blood supply.
Out with the old, in with the new.
No eating, no drinking, no breathing, no muss, no fuss,
that's the life for me.

I once made a salad slurrie.
I did not realize I could fit an entire head of lettuce in one glass!
The amount of calories I would have saved from blending.
were spent setting up and cleaning the blender.
It's only worth it if done in mass quantities or if I have no teeth.

I want documentation!
Doctors will gladly give amputees bionic limbs,

even if I agreed to pay them an arm and a leg.:- )

"Extropians look at the human body and say,
Isn't this a marvel of nature, but I think we can do a little bit better."
Mommy has poor distribution of resources.
We are made of C, H, and O because they are so abundant and flexible,
but now our mother is telling us how to build bones out of titanium
and brains from diamond.
I am still dying, my centuries are numbered, so I am far from optimal.

Good books are hard to find.
White cells use them to help fight germs too( rads not books).

I have lists of the leading causes of human death,
but what are the leading causes of cell death?
I looked but could not find anything.
A body count would be helpful.

Hey, thanks.
That's a pleasant and uncommon response.
I admit,
there is quite a difference between causing excess free radicals and
suicide.

Less body work = less heat.
Molecular agitation is another reason I do not want to use many body parts.

Clinch every muscle in your body for a few minutes
and see if you heart is not racing.
It won't build alot of strength
and won't put alot of strain on most bones,
you are right.
About endorphins,
have you ever heard of anyone being able to release them at will?
