Built For Exercise

Ever notice how some people have the get up and go to work out every day while others struggle to make it to the gym 2 or 3 times a week? As it turns out, there may be a genetic predisposition for exercise. In a joint study between the University of Alberta and University of California Riverside, scientists compared typical lab mice to those selectively bred for activity. They found a direct correlation between digit length and voluntary desire to exercise.

The Bigger Picture: Over the years, there's been a number of theories delving into the relationship between behavior, personality traits and hand dimensions. Some amount to no more than locker room mythology while others trend closer to validity. Whatever the case, you have the ability to override tendencies. You can decide for yourself to eat right and exercise regularly. The discipline might come easier to some than others, but the benefits extend to everyone.
