Feeling lazy today? Itsa国际传媒檚 OK sa国际传媒� yousa国际传媒檙e actually hardwired to feel like that, according to a study from the University of British Columbia.
The findings, published in the October edition of Neuropsychologia, found that the struggle is real.

Researchers recruited young adults for the study, put them in front of a computer and gave them the controls to an on-screen avatar.
Then, small images showing physical activity, or inactivity, flashed on the screen.
The young adults had to move their avatar as quickly as possible towards the pictures of activity and away from the pictures of inactivity, and vice versa.
By recording what was happening in their brains, researchers found that moving away from the active pictures was much harder for the subjectssa国际传媒� brains.
That came despite the fact that the subjects moved much faster when they moved towards the active pictures.
sa国际传媒淭he exciting novelty of our study is that it shows this faster avoidance of physical inactivity comes at a costsa国际传媒攁nd that is an increased involvement of brain resources,sa国际传媒� Boisgontier, who is a postdoctoral researcher in UBCsa国际传媒檚 brain behaviour lab at the department of physical therapy, said.
