Abstract: An apparatus and method for operably connecting a first person to a second person. The apparatus comprises a wrist strap having first and second ends sized to closely extend around a wrist of a first person and a coupling formed of a first coupling half located at the first end and a second coupling half located at the second end. The first and second coupling ends are lockably engageable with each other. The coupling has a pair of buttons to opposed sides thereof wherein the pair of buttons cooperate to disengage the second coupling half from the first coupling half and a connector extending from the wrist strap member connectable to a second person. The method comprises lockably and closely securing the wrist strap to a wrist of the first person, and securing a connector extending from the first wrist strap to a second user.

Abstract: A non-invasive method to measure total body tissue iron stores comprising recovering iron released from total ferritin contained in a body fluid sample derived from a host, measuring the ferritin-iron in the total ferritin and thereby determining total body tissue iron stores. Such an assay is utilized for diagnosing negative iron balance as well as positive iron balance, wherein the latter promotes cancer, coronary artery disease, atherosclerosis, and hepatic failure among other diseases, as well as the susceptibility to such diseases.
