If you are feeling crummy, vacuum up the crumbs around you. When was the last time you vacuumed under the cushions of your couch? It is amazing what it can collect. And surely you do not eat in your bed but if you do, get to vacuuming it as well. Eat at your desk? You are not alone. Pick up your keyboard and shake out the crumbs then clean under your keyboard. Take a close look at what is closest to you as it truly does affect you the most.
