Why you can't live longer

Bryan Johnson has become famous for his extreme approach to anti-aging. Using his own body, Johnson regularly tests new technologies, exercise routines, diets, and supplements to test the impacts on cell degradation. However, some experts believe that he is either wasting his time or the whole thing is just a clever marketing ploy to develop a health business. While healthy eating, exercise, and generally looking after your body has been shown to improve longevity, we seem to now be hitting a brick wall, with the increase of average life expectancy dramatically slowing down or even stopping in some countries. On top of this brain health may not be completely linked to body health, causing people to question weather it's worth keeping our bodies alive if our brains can't keep pace. 🚀 Discover deep-dive engineering stories and breakthrough technologies on Interesting Engineering: https://www.youtube.com/@interestingengineeringie 🪖 Explore military innovation and defense technology on Military Mechanics: https://www.youtube.com/@militarymechanicsie 🔔 Subscribe to IE Brief for daily updates on the discoveries, technologies, and global developments shaping our world: https://www.youtube.com/@ienews-brief 🔬 Complex tech, simply explained.
