After tens of thousands of years with virtually no way of avoiding the physical deterioration of aging, humanity is finally reaching the scientific and technological level necessary to repair the cellular and molecular damage of aging, thus preventing age-related diseases — such as Alzheimer's, cancer and cardiovascular diseases — and rejuvenating the body as a whole. However, we're not there yet, and to undo aging as soon as possible, we need robust cooperation and coordination at a global level, integrating the efforts of scientists, companies and organizations of a diverse nature. For that to happen, easy communication is essential, and despite English presently being the most international language, it's not a proper global language, as it's not reasonably well spoken and understood by all of the world sectors that would participate in the global effort to undo aging. To further facilitate this worldwide coordination and cooperation in the rejuvenation area by reducing language barriers, NTZ provides services in any language, coordinating a network of linguists built throughout years of experience in the area.
