India, Feb. 6 -- Indian doctor Shikhar Ganjoo sparked controversy on social media after mocking US millionaire and anti-ageing advocate Bryan Johnson following his abrupt departure from Nikhil Kamath's podcast due to air pollution concerns.

Taking to X, Dr. Ganjoo wrote, "Longevity rant is a laughable, deluded OCD tirade. Every word reeks of pseudo-scientific desperation, turning his life into a pompous farce. His rigid rituals are not inspiring but a miserable mockery of living."
