Zomato CEO's Temple Device Sparks Debate
Deepinder Goyal, the CEO of Zomato, has been wearing a small device called Temple on his temple.
This device is part of his personal research into how gravity might affect the brain.
The device measures blood flow in the brain, which Goyal believes could help understand aging.
He has been testing it for about a year.
However, some doctors say the device is not scientifically proven and more research is needed.
The device is not for sale and is only used for research.
Deepinder Goyal, CEO of Zomato, introduced the Temple Device, a wearable that measures brain blood flow.
The device is part of Goyal's Gravity Aging Hypothesis, which suggests gravity reduces brain blood flow, potentially affecting aging.
Goyal has been using the device for about a year as part of ongoing testing.
The device is not a medical product and lacks regulatory approval.
Experts question the device's efficacy, stating it cannot reliably measure brain blood flow or predict neurological health.
