that's not it's intention, but it's possible. my lockboxes are designed for keeping and safeguarding personal items. if you know how to control your emotions, i think you can actually increase or decrease your heart rate just by putting certain thoughts in your head. if you make yourself really angry, your rate will probably increase, opening the box, or if you know how to calm yourself, that may also open the box. an emergency pill box is not a bad idea though.
