And as I say, most of them really die very horribly, 80 is very bad for you. now that means, that is really bizarre that one should ask the question why should we defy aging.

We also refer to subclinical conditions.

We call it.....make it clear you see that. This is kind of tube over here. Let me draw the blood

In fact scientist are theorizing that this age proteins may play an important role in the development of atherosclerosis, as well as certain complications of diabetes and chronic kidney failure.

It would look something like that.

Yes. She had multiple sclerosis.

And the processes that cause this are things like arteriosclerosis for the large vessels or arteriolosclerosis for the small vessels.

As you look at this you will see that the movement energy, I'm going to assume for the two cases is similar, so similar sized bar.

Here's an example from Kevin Eggan's lab at Harvard.

And I developed a chronic disease for which there is no cure.

All of that connective wiring must be insulated with something called myelin.

Neither of them attended university.

Artery up here, artery over here, and then vein in the other two spots.

His vitals are spiking.

And then, when the heart is ready to pump it back out, it goes into this artery, and the name of it is the aorta.

And then I wondered was there any relationship between how much people changed their diet and lifestyle whichever group they were in and the changes in PSA?

In the case of rheumatoid arthritis, the immune system attacks the cartilage around the joints.

The motion creates the real time pulsation that is shown visually in a form of light

Now, to start the journey, it's gonna have to out of the left ventricle and into the largest artery of the body.

And let me actually show you where the blood vessels come from. These are called coronary vessels I just write the word coronary here.

It doesn't have any veins.

Coronary vessels So, coronary artery and vein.

And the veins actually drain into a spot , directly into the right atrium.

And on the right you actually see a carotid artery that was engineered.

This is one mechanism by which the bacterium Bacteroides fragilis prevents a mouse version of multiple sclerosis.

Remove the ties that bind...

Right it's gonna have to go away from the heart. So that's the aorta. The aorta actually has the little arch like that.

Smelling salts.

If the artery gets nicked, how long do i have?

And actually it stop there because of my arrows, but you can actually see now deoxygenated blood kind of goes from the right ventricle, through the pulmonary trunk, through the arteries and into the left and right lung.

I'm going to do some surgery here.

But, actually lungs are kind of interesting in the sense that there is a lot of mixing going on.

He's dying. Coronary blockage.

Remember the heart itself is a muscle. It itself needs oxygen.

And I hesitated there just to make sure I got that because it's taking blood away from the heart.

No lesions. No aneurysms.

MAP's at 55.

In the jugular preferably. okay.

In your jugular on the side of your neck.

Midway up her right thigh?

I could just write artery and vein and essentially they would be behaving this way.

So these two veins, the superior vena cava and the inferior vena cava, are dragging the blood back to the heart, and, generally speaking, these are all considered, of course, veins.

His name is Mike, and he is uniformly impaired on cognition, vision, walking, sensation.

I think she cut both arteries. I could hardly feel her pulse.

Let's say this one goes towards my foot, and this is going to be now an even smaller artery.
