Age-reversing Bryan Johnson says India should solve air pollution, not cancer. His tips

While some social media users appreciated Bryan Johnson’s focus on air pollution, others felt his methods were excessive.

Age-reversal entrepreneur Bryan Johnson has once again drawn attention to India's air pollution crisis, offering advice on how to minimise its harmful effects. In a recent post on X (formerly Twitter), Johnson, 45, highlighted the severity of the issue, claiming that "India would save more years of life by solving air pollution than curing cancer."

Accompanying his post, Johnson shared a video featuring his associate explaining the strategies they used to combat air pollution during a recent visit to India. Johnson was in the country in December to promote his book on age reversal and engaged in discussions with young entrepreneurs about his venture, Don’t Die.

In the video, Johnson’s associate detailed the steps they took while staying in Mumbai to protect themselves from the city's poor air quality. "We carried portable air filters everywhere we went to ensure clean air," she said, as footage showed Johnson transporting an air purifier across the city.

The team monitored air quality with portable devices and avoided locations with poor indoor air conditions, such as the hotel gym. “In cars, we kept the windows closed, and in hotel rooms, we used air conditioning to circulate air,” she explained. For outdoor trips, they wore N96 masks to minimise exposure.

"Each country has its silent killer," the associate noted. "In India, it’s pollution. In America, it’s obesity. The most important thing is to understand your environment."

While some social media users appreciated Johnson’s focus on air pollution, others felt his methods were excessive. “Air pollution is a major challenge for India’s future—not just a health issue but an economic and social one as well,” one user wrote in support.

Another praised his efforts, saying, “If we are to save the planet, we must start saving ourselves. This is a great way to start.”

However, a dissenting user criticised the approach, stating, “I’m not carrying around an air filter when I travel. If you’re visiting for a short period, this level of obsession seems unnecessary.”
