And what's interesting about BPA is that it's such a potent estrogen that it was actually once considered for use as a synthetic estrogen in hormone placement therapy.

So when you develop a cancerous cell in your breast, aromatase converts androgens into estrogens, and that estrogen turns on or promotes the growth of that cancer so that it turns into a tumor and spreads.

And I have concocted a questionnaire to see to what degree you express dopamine, serotonin, estrogen and testosterone.

But what atrazine does is it turns on an enzyme, the machinery if you will, aromatase, that converts testosterone into estrogen.

Because it turns out that the number one cancer in women, breast cancer, is regulated by estrogen and by this enzyme aromatase.

I would even say that with Viagra, estrogen replacement, hip replacements and the incredibly interesting women

And as a result, these exposed males lose their testosterone, they're chemically castrated, and they're subsequently feminized because now they're making the female hormone.

So we're dosing our babies, our newborns, our infants, with a synthetic estrogen.

It's a material hardener and synthetic estrogen that's found in the lining of canned foods and some plastics.

PJC So speaking of estrogen, one of the other compounds that Tyrone talks about in the film is something called bisphenol A, BPA, which has been in the news recently.

And what was remarkable about it was in the past when we think of chemical messengers within the body, we thought of complicated things like estrogen and insulin, or nerve transmission.

Women's ability to find the right word rapidly, basic articulation goes up in the middle of the menstrual cycle, when estrogen levels peak.

So what kind of hormones are these?

It's interesting, because it was six years ago when I was pregnant with my first child that I discovered that the most commonly used preservative in baby care products mimics estrogen when it gets into the human body.

I would even say that with Viagra, estrogen replacement, hip replacements and the incredibly interesting women women have never been as interesting as they are now.

These hormones are similar to hormones that we have in our bodies.

And this is not just philosophical, it's already known, that chemicals like diethylstilbestrol and estrogen, PCBs, DDT cross the placenta and effectively determine the likelihood of developing breast cancer and obesity and diabetes already when the baby's in the womb.

Women's ability to find the right word rapidly, basic articulation goes up in the middle of the menstrual cycle, when estrogen levels peak.

And the reason is that these hormones, like the insulin and the IGF hormones and the TOR pathway, they're essential.

Incentives for participation

Part of it's on the outside, and it's catching the hormone as it comes by in green.

The tigress...

And she?

And that's really mediated by the sex hormones.

And we have testosterone.

There's lots of hormones. There's testosterone, adrenalin.

To overcome her?

Third Female

All of a sudden having conversation and communications with the estrogens, the progesterones, saying, I'm here to stay, plant me, building this incredible trilinear fetus that becomes, within 44 days, something that you can recognize, and then at nine weeks is really kind of a little human being.

And also, there are other ways of activating FOXO that don't even involve insulin or IGF 1 that might even be safer.

I spent the last couple of years looking at the science of human motivation, particularly the dynamics of extrinsic motivators and intrinsic motivators.

And the hormone IGF 1 promotes growth.

It told us about hormone replacement therapy.

Laser quality ink jet printers

The daf 2 hormone receptor is very similar to the receptor for the hormone insulin and IGF 1.

She'll holler on me.

There's a hind. There's a doe.

You can engineer a prairie vole to become monogamous when it's naturally polygamous.

Those females, they're not trying to.

It's only the female mosquito that will actually bite you.

It's just the female.

In addition a new method called separation of isotopes by laser excitation (SILEX) is being developed.

Insulin is a hormone that promotes the uptake of nutrients into your tissues after you eat a meal.

Giving the latter group exogenous growth hormone is futile, because their immune systems react to the foreign protein by producing antibodies. Although the hormone may stimulate growth for a short period, the antibodies soon bind and neutralize it.

And this was something that was really brought home to me a year ago when I found out I was pregnant and the first scan revealed that my baby had a birth defect associated with exposure to estrogenic chemicals in the womb and the second scan revealed no heartbeat.
