What if I told you life insurance companies can predict, almost to the month, when you’re going to die? That’s exactly what Gary Brecka, a human biologist and former mortality expert, used to do—until he uncovered something shocking. After years of analyzing blood work and medical records, he realized that the biggest predictors of disease and early death aren’t genetic—they’re modifiable. Now, he’s using that knowledge to help people optimize their health and extend their lifespan. In this episode of The Dr. Hyman Show, we discuss:

• How insurance companies use hidden health data to predict life expectancy with stunning accuracy.
• The biggest factors that shorten lifespan—and why most of them are within our control.
• Why vitamin deficiencies, especially vitamin D, are quietly fueling chronic disease.
• How the right biohacking tools, like red light therapy and oxygen optimization, can reverse aging.
• What you can do today to take control of your health and longevity.

This conversation will change the way you think about your own health.
