Objectives: To explore the link between low self-control during adolescence and health problems in early adulthood. Methods: Using data from the National Longitudinal Study of Adolescent Health, we examined the relationship between varying levels of self-control and the likelihood of being diagnosed with a variety of physical and brainbased health conditions. Results: Results from logistic regression analyses indicated that subjects with lower levels of self-control had significantly higher odds of being diagnosed with 9 of the 10 health outcomes. Conclusions: Targeting the development of selfcontrol in childhood and adolescence may be valuable in preventing future health problems.

The nature of inter-group relations among prehistoric hunter-gatherers remains disputed, with arguments in favour and against the existence of warfare before the development of sedentary societies. Here we report on a case of inter-group violence towards a group of hunter-gatherers from Nataruk, west of Lake Turkana, which during the late Pleistocene/early Holocene period extended about 30 km beyond its present-day shore. Ten of the twelve articulated skeletons found at Nataruk show evidence of having died violently at the edge of a lagoon, into which some of the bodies fell. The remains from Nataruk are unique, preserved by the particular conditions of the lagoon with no evidence of deliberate burial. They offer a rare glimpse into the life and death of past foraging people, and evidence that warfare was part of the repertoire of inter-group relations among prehistoric hunter-gatherers.
