Zomato CEO Deepinder Goyal was seen wearing an experimental device on his temple during a podcast, sparking widespread social media speculation. The device, part of Goyal's personal research into the 'Gravity Ageing Hypothesis' under his company Eternal, is designed to track blood flow to the brain as an indicator of neurological health and aging. Goyal has committed personal funds to this research, which he describes as open-source and aimed at scientific progress in human longevity, noting it is not a Zomato product and not yet commercially available.
