Being said all that, recently I've read many similar stories of sharp fall from the height of success. It seems, many people working in the private sectors are vulnerable to "keep running, or you are doomed" like theory. The social and economical structure in many countries, even many developing countries, are different which prevent the "fall from the cliff" like cases. Strong family bonds, affordable permanent ownership of properties etc are key to stability.
Many EU countries have balanced structure where you can choose to slow down in your career path, and to enjoy life. Although government in those countries charge a huge percentage of tax, they take care of their citizens to prevent the sharp fall in career and life.
Perhaps, too strong capitalism, attention to too many distractions all over the world, relying on numbers instead of the quality in those numbers etc are affecting the whole domestic socio-economic balance.
