The author traces modern ideas of masculinity from the inability of older generations to deal with the horrors of war, to the mob mentality of football terraces or Fight Club and the disturbing rise of mental health problems among men - especially young men - today. While we struggle with the idea that there is a single version of masculinity worth aspiring to, depression and suicide among men have reached unprecedented levels. Man Up looks at the challenges and pressures on men today, and suggests ways to survive.
