objects at rest tend to remain at rest

Danish researchers have found that adults who were overweight kids have a much higher tendency to having early health problems as adults - heart issues, diabetes, etc - than adults who weren't overweight as youngsters.

For some reason, they didn't have access to the weight of the survey subjects as adults, so they couldn't say for sure whether the "risk was risk was due to the effects of being overweight when young or because overweight children are more likely to become overweight adults."

My vote is for the latter. Inertia is a powerful thing. Objects at rest tend to stay at rest. And we all know how hard it is to remove a few pounds once you put 'em on. But still, another good reason (as if you needed it) to cut back on Junior's Double Big Mac habit and make the kids go outside and play some football or something instead of watching American Idol.
