The De-Man-isation

I began reading articles about how the last century has forced the Alpha-Males to turn into Beta-Males. It discussed about the shift from manual jobs to the so called white-collar jobs and the blue-collar jobs being looked down upon. Much of the physical exercise, men in the 20th century got from their work, which now is being replaced by machines. The type of food we eat today has severely affected our lifestyle i.e. the shift from fats to carbs.
