Conclusion The hypothesis was rejected. In a dose–response manner, occupational physical activity increased the risk for LTSA (Long-term sickness absence), while leisure-time physical activity decreased the risk for LTSA. The findings indicate opposing effects of occupational and leisure-time physical activity on global health.
Interesting. We are always told of the benefits of activity, but in the context of "work" it seems that it is not as healthy. There will be lots of factors here - the repetitive nature of work, the psychological stress, the fact that physical jobs tend to be low paid and so other elements of health may be missing - but I like to think that this illustrates the value of what Mark Sisson talks about in terms of play. Work by definition is not playful.
