Longevity is the new frontier, and Indian founders are obsessing over it.

Take Eternal founder Deepinder Goyal, for instance, whose newest passion projects centred on ageing and longevity, came to the fore earlier this week.

Called Temple, the endeavour is expected to be around selling wearable devices that monitor brain health. While Goyal has not officially launched Temple, images of him wearing the device have emerged in the past week.

This comes hot on the heels of Goyal’s Continue Research unveiling its maiden hypothesis.

Called Gravity Ageing, Continue Research claims that cerebral blood flow (CBF) or how blood reaches the brain, plays a crucial role in ageing.

Among the new bets from the Eternal founder — another one being LAT Aerospace — Continue Research has not only attracted attention but some criticism too. Its hypothesis in particular is being debated intensely, with many calling it untested and unscientific.

But this just scratches the surface of a wider longevity and healthtech movement gathering steam in India. While Goyal’s high profile has turned the spotlight on Continue and Temple, there are indications that this is the dawn of a healthtech 2.0 moment.

The Buzz Around Temple

Although Continue has been conducting research in private for more than a year, Goyal’s new pet project first drew public attention in October 2024 when he referred to it as his ‘personal health and wellness team’.

Not much was revealed after that until this week when Continue unveiled its first public hypothesis, and soon after that images of Goyal wearing the ‘Temple’ device also emerged.

The hypothesis suggests that gravity’s constant downward pull on blood flow to the brain may be a key driver of human ageing. According to the hypothesis, gravity can reduce blood flow to the brain by up to 17% when people are standing or sitting upright.

The research further claims that over a period of decades, such reduced circulation may weaken the hypothalamus and brainstem, two critical regions responsible for metabolism, hormonal balance, inflammation, and autonomic functions. Their gradual decline, the hypothesis argues, could trigger the ageing process.

While the hypothesis emphasises that gravity isn’t the........
