Traditionally, farmers try to reduce their exposure to risks like crop failure (from bad rains or crop parasites) by minimising their investment in farming inputs.

Despite the incredibly high risk, predator following has persisted over evolutionary time. Perhaps, Natterson-Horowitz and Bowers suggest,

but their risks come in other ways. In the United states, according to the Centers for Disease Control, one third of teenage deaths are associated with car crashes.

But the risk of death is distributed not evenly among teenagers. Like otters, males are more likely to die than females
