Imagine my surprise when I desired to talk about why we care, and I saw what I care elementally meant: iodine, calcium and rhenium.

​

Iodine

[Our bodies use it to make thyroid hormone, which the brain needs to grow and the body needs to run.]

​

Calcium

[It builds our bones. A wave of calcium wakes the egg at fertilization, and over a lifetime it marks our mortality.]

​

Our brain, our bones, our humanity.

​

Rhenium

[Mendeleev left a space for it in his periodic table decades before anyone found it. We knew it had to exist before we could see it.]

[It was the last stable, natural element to be discovered, in 1925. One of the three people who found it was a woman, Ida Tacke.]

[It's one of the rarest elements on Earth, about one part per billion. It never shows up on its own. It hides inside other ores.]

[It holds up under some of the fiercest heat there is, over 3,000 °C, inside jet engines and rockets.]

​

This spark, this rare material that just can ignite. That's what care does. It holds under fire, because we can't stop caring. That is the power of care.

​

That's how eight billion people are kept alive. Because we care under pressure. Under not knowing.

​

The Magic

That is the magic of our not only fertility and finite mortality, but our fecundity, our ability to birth beyond our biology. Our imagination combined with our curiosity can make dreams come true. Together. When we know better.

​

That's what we're here for. That's what we care about. Making dreams come true. In each other.

​

When people ask, let them know.

Let Them KNOW What You Need, To Be Misery-Free and Free To Care.
