Born lazy?
Wow! People may really just be born to be couch potatoes! Such is the possible results from recent studies with mice.
It seems they have found genetic indicators that may affect the level of activity the subject is inclined to participate in. This has some serious implications on the health and fitness industry which has for decades proclaimed that everyone can just do it. It may help to explain why some people, despite knowing just how could exercise could be for them, and realizing they need to increase their activity level, just can’t seem to get started.
Now us lazy folks have an excuse. 
Of course, on a scary note, can you imagine genetic screening for laziness?
