Your fate is in your hands? Handedness, digit ratio (2D:4D), and selection to a national talent development system.

Over the past decade a small evidence base has highlighted the potential importance of seemingly innocuous variables related to one's hands, such as hand dominance and the relative length of the second and fourth digits (2D:4D ratio), to success in sport. This study compared 2D:4D digit ratio and handedness among handball players selected to advance in a national talent development system with those not selected. Participants included 480 youth handball players (240 females and 240 males) being considered as part of the talent selection programme for the German Youth National team.

Physical activity and successful aging in Canadian older adults.

Rowe and Kahn (1987) proposed that successful aging is the balance of three components: absence of disease and disease-related disability, high functional capacity, and active engagement with life. This study examines the relationship between physical activity involvement and successful aging in Canadian older adults using data from the Canadian Community Health Survey, cycle 2.1 (N = 12,042).
