“People Don’t Die From Disease—They Die From Gravity”
Swapnil Srivastav took to social media praising Goyal’s radical approach: “Deepinder wearing a device called Temple to track blood flow to the brain and it’s wild and fascinating. His belief is simple and radical—people don’t die because of disease. They die because of gravity”.
According to Goyal’s theory, gravity constantly pulls blood downward, reducing cerebral circulation over time, which accelerates ageing and cognitive decline. The Temple device continuously monitors this critical biomarker to validate his hypothesis.

What Makes Temple Revolutionary?
The compact gold-colored sensor worn near the temple uses advanced technology combining sensors and AI to interpret cerebral blood flow patterns. The device provides insights into:
- Memory and focus levels
- Stress responses
- Sleep quality
- Mental fatigue
- Cognitive decline indicators
Goyal explained the device emerged from his personal health optimization journey involving blood tracking, fasting, meditation, and hyperbaric chamber routines, eventually leading to the Gravity Ageing Hypothesis.
The Science Behind the Theory
Goyal’s research suggests that humans spending most time upright causes gravity to impair brain circulation. His team’s internal testing revealed that six weeks of daily inversion table use for over ten minutes increased average brain flow by seven percent, potentially reversing nearly a decade of age-related decline.
The research draws parallels to bats, among the longest-living mammals relative to size, whose inverted position with heads below hearts may explain their exceptional longevity.

Industry Response and Future Implications
While experts debate the Gravity Ageing Hypothesis validity, Goyal maintains that brain blood flow is an established biomarker for ageing and cognition, making Temple relevant regardless of whether his specific theory proves correct.
Temple will remain a specialized venture separate from Eternal, emphasizing Goyal’s commitment to scientific research over commercial exploitation. If successful, the device could pioneer a new product category focused on brain flow as a core physiological metric with global implications for anti-aging and cognitive health.
The device isn’t ready for consumers yet, but Goyal’s public appearances wearing Temple suggest development is advancing rapidly, potentially marking Eternal’s ambitious shift from food-tech into deep-tech medical innovation.
