We treat the immune system like an emergency contact.

I started noticing how much attention it gets once something goes wrong, and how little we think about it the rest of the time.

When everything is fine, the advice gets pretty short.

• Sleep.
• Eat well.
• Move your body.
• Wash your hands.
• Don’t let your kids lick trash cans.

Then wait.

I kept wondering about all the ordinary days in between.

My best friend Vivian grew up in the nutraceutical industry and has the same exhausting character flaw I do.

Care can belong to the ordinary days, too. The days when everything is going well. The days we’re busy living.

Those are the days we want more of.
