I never understood this nordic lifestyle I saw in Scandinavia, Benelux and Northern Germany where people refuse to take a proper lunch break and just eat some random cold food in front of their computer for the sake of productivity for their employer. It's just depressing to see and unhealthy in the long term.
In southern Europe(Austria) having a walk to the bistro for a warm lunch with freshly cooked quality food, away form my desk is not only healthy but also gives me a refreshing physical, mental and morale boost.
Sitting glued to my chair in front of the computer for 8 hours straight is not only unhealthy but would just burn me out quickly.
