you right lenny.. I didn't read the original link which I overlooked but having now done so I see that the laziness more specifically refered to physical activity rather than laziness persay.....

as the study just looked at mice and their use of a wheel it was to say the least rather limiting.. some mice may just dislike wheels
differences may also be down to metabolic rates or dare I say but perhaps the less athletic mice were more academically biased and instead of wasting energy on a wheel put it to solving the ultimate question... not the first time such a possibility has been raised as arthur dent learned from Fladi bardfast in Hichhikers guide to the galaxy....

similarly the study looks as if it was incredible small (given that the article pointed out the specific action of three 'lazy, mice) and one could aver that perhaps the researchers themselves exhibited lasiness in the smallness of the data set and the failure to measure metabolism ...

I think the real problem is determining that failure to do a treadmill exercise is laziness... for some of us its just down to boredom... a possible explaination for the mouse that used the wheel as a viewing point...

perhaps to truely answer this question we need first to define what we mean by lazy
