India's most respected bootstrapped founder, who built Zerodha to profitability without VC money and openly caps headcount to protect culture, disclosed at 44 that he had a mild stroke. He named the causes plainly: poor sleep, exhaustion, dehydration, overworking, grief. The doctor's line to him is the whole argument for this question: even a fit person who takes care of himself needs to know when to shift the gears down. For an Indian founder marinating in hustle culture, this is the credible local proof that never unplugging is not commitment, it is compounding risk.

• A fit, disciplined, successful founder is not immune. Kamath attributed his stroke to sleep debt, exhaustion, and overwork, not a lack of grit.
• The signal to rest comes before the crisis, not after it. His doctors told him to shift down; the body sent the invoice first.
• Recovery cost him months (three to six for full recovery), far more than the one day off a week that would have been the cheaper insurance.
