Imagine if tomorrow, it was announced there had been a discovery that doubled average human life expectancy to 150. There would be happiness, but there would also be chaos. How many people would quit all the things they'd told themselves they were too old to change? The job they were grinding out until retirement. The marriage they'd resigned themselves to? Imagine billions of people getting pulled backwards back across the midlife crisis line, realizing that yes, maybe there IS more to life than "this". The days and weeks after that announcement would be some of the most chaotic the world has ever seen.
