Analog techno is the thing.

Rs 85,000. For a sticker that measures your face and calls it your brain. I am a Cardiothoracic Surgeon. Every day I hold a human heart in my hands and I fight to keep blood flowing to the brain. So when I see a device that claims to measure BrainFlow from your temple, I cannot stay silent. Because what Temple is measuring is not your brain. It is your scalp. And that difference is not small. That difference is everything. Let me make it simple for you. Put your finger on your temple. Feel that pulse. That is your superficial temporal artery. That artery is a branch of the EXTERNAL carotid artery. It sits OUTSIDE your skull. Its job is to supply blood to your scalp, your temple, your face, your ear. Your brain does NOT run on this artery. Your brain runs on the INTERNAL carotid arteries and the vertebral arteries. They go deep inside. They are protected by bone, by muscle, by dura. So when someone tells you a sticker on your temple is measuring your BrainFlow, I have to ask - how? Temple uses PPG. Photoplethysmography. The same light-based technology in your smartwatch. It shines light into the skin and sees how much blood is moving under it. At the wrist, it measures the wrist. At the temple, it measures the temple. It cannot magically see through skin, scalp, temporalis muscle, skull bone, meninges, and then tell you what is happening inside your cortex. Light does not work like that. If it did, we would not need MRI, CT angiography, transcranial Doppler, or invasive monitoring in cardiac and neurosurgery. In the OT, when I want to know cerebral perfusion, I do not put a sticker on the temple. I rely on validated monitors, on blood pressure, on cardiac output, on cerebral oximetry that has been tested in thousands of patients. Because brain blood flow is not the same as scalp blood flow. When you are embarrassed, your face flushes. Your temporal artery dilates. Does that mean your brain just got smarter? When you drink coffee, when you exercise, when you get angry, when you stand up from a chair - your scalp flow changes. Your brain flow, thankfully, stays remarkably stable because of autoregulation. That is how we survive. So if scalp flow and brain flow move together during exercise, that does not prove you are measuring the brain. That just proves both went up because your heart is pumping harder. This is what we call correlation without causation. And with only 23 healthy volunteers in an unpublished, company-funded preprint, that is not validation. That is a pilot study. In medicine, we do not sell a pilot study for Rs 85,000 ($904 USD). And then there is this new word - Entropy. A score from 1 to 250 to tell you the cost of being alive. I can tell you, there is no validated medical biomarker called Entropy that you can measure from your temple and use to predict ageing, longevity, or brain health. Metabolic carts, VO2 max testing, lab-based calorimetry - these took decades of validation. You cannot replace them with a proprietary algorithm and call it a discovery. Now, Mr. Goyal says - Temple is not a medical device, it is a wellness device. Then why call it BrainFlow? Why talk about brain ageing? Why talk about gravity ageing hypothesis? Why talk about cerebral blood flow? You cannot market like a medical breakthrough and then hide behind a wellness disclaimer when doctors ask for proof. And the argument - If it does not work, people will return it in 14 days, so it cannot be a scam. Sir, with respect, a patient cannot know in 14 days if his brain blood flow measurement is accurate. He has no gold standard at home to compare it with. He will see a number go up and down, he will feel reassured, he will think he is tracking his brain. That is exactly the danger. A 14-day return policy is not peer review. Spending 30 million dollars is not peer review. Having a good reputation in food delivery is not peer review. In medicine,we have a simple rule. First, do no harm. Second, prove it before you sell.

Deeply saddened by the sudden demise of @KAnantrao sir. Our association goes back almost 20 years. He was a guide, mentor, and like an elder brother to me. He was a speaker at many Definedge conferences and the one who would bring people together for the evening sessions before and during our events. I have rarely seen communication skills like his. He could speak fluently in many languages.. would beautifully use shayari and shlokas in conversations.. and had incredible depth of market knowledge. He had visited the Definedge office just last week and we had discussed so many plans ahead. But destiny had other plans. Sir.. you will be missed forever. Even the heavens would cherish your presence and company. Rest in peace 🙏 His last Whats app Status.

Without telling me your age. What is the first video game you played? GIFS ONLY!!!
