Overview
- Deepinder Goyal wore the small metallic sensor on Raj Shamani’s podcast, describing Temple as an experimental device that monitors cerebral blood flow in real time.
- It is tied to Goyal’s Gravity Ageing Hypothesis and his Eternal/Continue Research initiatives, with reports of roughly $25 million in personal funding and about a year of self-testing.
- AIIMS Delhi radiologist Dr. Suvrankar Datta publicly called the device a “fancy toy” with “zero scientific standing” and urged caution against spending on unproven health tech.
- Reporters note there are no published technical details, clinical trials, or a regulatory pathway, and say comparable optical approaches in academia (such as fNIRS and diffuse correlation) remain research tools.
- Temple is not a Zomato product and is not for sale, and clinicians emphasize that tracking brain blood flow does not constitute evidence for slowing or reversing ageing.
