Technology in The Suite: Simple tools can make life easier for aging adults including those suffering from arthritis. Does arthritis or hand weakness prevent you from doing simple daily activities like opening your milk carton? Consider using a Milk carton opener. It allows you to open a milk carton in two easy steps. Split the opening to open the carton flaps and then pierce. Now you can have your cereal. A Milk Carton opener can be purchased at sites such as North Coast Medical for around $19.
