When your blood is tested, ask for your white blood cell count and specifically, your neutrophil. When your white blood cell count is low, do what you can to prevent infections. Know the signs of infection and what to do if you have them.
Like the face and body, ground coffee beans can be used to exfoliate the scalp. As a bi-weekly treatment, massage grounds into hair and scalp before shampooing, which can help to remove unwanted buildup. Just be aware that it might get a little messy. Warning: Coffee can stain lighter hair, so skip if you're a blonde.
Some bags (such as those used at Blue Bottle) use a one-way valve that allows the fresh coffee to off-gas its initial CO2 without bursting the bag and can be resealed. Keeping your beans snug in one of the good resealable bags is a fine way of staying fresh.
