Don’t cross your legs!!!!

For those who often cross their legs when sitting down for a long period of time, 3 unhealthy things will happen to them:

1) Their backbone tends to become "C" shape.
2) They will have neck aches and backaches on one side.
3) For ladies, their shoulder will tend to slant one sided causing their bra strap to slip down the slanted shoulder.

Office girls who cross their legs, please take note!
