G.Lewis's analysis of a 1986 survey on psychiatric morbidity (panic attacks, phobias, depression) using a representative sample of 6, 437 people, found that 31 percent of them were fucked, as opposed to only 22 percent in 1977.
Add to this 31 percent other low-serotonin problems such as violence and aggression, and you're pretty much looking at half the population.
