Where did the tears come from?
My best guess, strange as it might sound, is that our ancestors were in the habit of punching each other on the nose. Such injuries would have resulted in copious tear production. And there is an independent line of evidence to suggest that they were common. According to recent analysis by David Carrier and Michael Morgan from Utah University, the shape of human facial bones might well have evolved to withstand the physical trauma of frequent punching. Thickly buttressed facial bones are first seen in fossils of Australopithecus, which appeared following our split with chimpanzees. Carrier and Morgan further argue that Australopithecus was our first ancestor whose hand was capable of making a tight fist. So, the reason we weep now may well be that our ancestors discussed their differences by hitting each other in the face. Some of us still do, I suppose.

"She had suffered from severe organ failure following serious injuries to her body and brain. She was courageous in fighting for her life for so long against the odds but the trauma to her body was too severe for her to overcome," a statement released by Mount Elizabeth Hospital chief executive Kelvin Loh said.

"On Copacabana beach in Rio de Janeiro, 500,000 beans were scattered on the national flag and on 40-metre-long strips of red carpet, in a protest organised by the local NGO Rio de Paz.
"Hundreds of passersby stopped to gaze at the symbolic rivers of blood, which ran up to a wooden cross and a sign reading: ‘Brazil: half a million murders in 10 years. SHAME.’”
Cities with more than 500,000 inhabitants account for over 70% of homicides in Costa Rica, 68% in Guatemala, and 63% in El Salvador.
Crimes may be more likely to be reported in urban areas, skewing the statistics. In a study in Kenya, for example, urban inhabitants were more likely to report crimes than their rural counterparts.
In many countries, urban areas have a higher rate of violence using firearms. Fifty metropolitan areas surveyed in a recent U.S. study, representing 54% of the national population, accounted for 67% of firearms homicides.
While the size of cities does not appear to have a direct correlation with violent crime rates, a high rate of urbanization often correlates with greater violence.
Other factors that can exacerbate urban armed violence include: rates of unemployment; high proportions of youth; low levels of education; poor urban design; proliferation of firearms; and high density of informal settlements.
