Caffeine seems to have beneficial effects on psychomotor activity. Further well-designed studies are needed to consolidate these findings.

To describe the association between occupation and risk of suicide among working-age men and women in Canada. ⋯ The limited number of associations between occupational groups and suicide risk observed in this study suggests that, with few exceptions, the characteristics of specific occupations do not substantially influence the risk for suicide. There was a moderate gradient in suicide mortality risk relative to occupational skill level. Suicide prevention strategies in occupational settings should continue to emphasize efforts to restrict and limit access to lethal means, one of the few suicide prevention policies with proven effectiveness.
