Most people multitask, so most people don't sit down to eat

If you eat breakfast in the car, gobble lunch while working at your computer, and watch TV while cooking or eating dinner, you’ve got a lot of multitasking company.

About 62% of people in a nationally representative online survey say they are sometimes or often too busy to sit down to eat, and about nine out of 10 say they do other things while preparing meals. On top of that: 31% do not consistently wash their hands when switching tasks during meal preparation.
