After blocking US-based millionaire Bryan Johnson on X over his remark on Haridwar's air quality, Baba Ramdev invited him to Haridwar Yoggram to "explore India's yoga with a neutral and scientific perspective". "We are sharing a video with proof of Haridwar Yoggram's excellent AQI," Ramdev said. "The scientific approach to anti-ageing is rooted in yoga, Ayurveda, and nature," he added.
