Continuous partial attention makes it too easy to snack. Instead of waiting for the main meal, we fritter our hunger away on too many chips and salsa. We're full before the entree.
Replace chips with social media, and you start to see the excess wear and tear we put on our bodies and minds. We can't possibly consume all this information and still devour the main meal. It's like eating all the popcorn before the movie starts.
Unless we plan on taking the food home with us or putting on some extra weight, we better slow down and refocus our attention on why we decided to eat out in the first place.
If you're going to snack, do it in moderation, so you still have plenty of room left over to absorb the good stuff.
