To test whether handedness is associated with a change in longevity.
Archival survey.
British Isles.
All first class cricketers born before 1961 whose bowling hand was specified (right, n = 5041; left, n = 1132) in a comprehensive encyclopaedia.
Bowling hand and life span.
Regression analysis of the 5960 players born between 1840 and 1960 (3387 dead, 2573 alive) showed no significant relation between mortality and handedness (P = 0.3). Left handedness was, however, associated with an increased likelihood of death from unnatural causes (P = 0.03, log hazard 0.37, 95% confidence interval 0.04 to 0.70). This effect was especially related to deaths during warfare (P = 0.009, log hazard 0.53, 0.13 to 0.92).
Left handedness is not, in general, associated with an increase in mortality.
测试用手习惯是否与寿命变化相关。

在一本综合百科全书中明确了投球手惯用手（右，n = 5041；左，n = 1132）的所有1961年以前出生的一流板球运动员。
投球手惯用手和寿命。
对1840年至1960年间出生的5960名球员（3387名已故，2573名在世）进行回归分析，结果显示死亡率与用手习惯之间无显著关联（P = 0.3）。然而，左利手与非自然原因导致的死亡可能性增加有关（P = 0.03，对数风险0.37，95%置信区间0.04至0.70）。这种影响尤其与战争期间的死亡有关（P = 0.009，对数风险0.53，0.13至0.92）。
一般而言，左利手与死亡率增加无关。
