These materials are intended to assist men and women as they strive to improve their relationships and life goals. While we attempt to thoroughly address specific topics, it is not possible to include discussion of everything necessary to ensure a healthy and safe lifestyle in a presentation of this nature. Thus, this information must be understood as a tool for addressing life choices, rather than the advice of a medical professional. Likewise, to the extent that this information references practices or procedures that may enhance health or lifestyle, but which are not required by a statute, regulation, or standard, it cannot, and does not, create additional legal obligations. Finally, over time, we may modify rules and interpretations in light of new technology, information, or circumstances.
