Transyears: New endpoints for gerontology and geriatrics or confusing sources of variability?

It is important to make longitudinal cycles generally known and to advise everyone that the information may not be obtained from transverse studies, when subjects are not synchronized and when components vary as a function of age (14) and are beating (10,11). The contributions of a few test pilots who did and still do lifetime monitoring have paid off. But there is a need for a systematic government-supported endeavor, the same way as physicists did and do their monitoring on earth and now from satellites without applications for grants. Physiological monitoring should become a continuing routine of use in the ubiquitous transdisciplinary fields to which about-decadal as well as circadian cycles apply. We welcome physicists (15) who explain their field to biologists, and vice versa, we should follow their example (8). By matching the systematic environmental monitoring, it is now time for biomedicine as a whole to provide systematically transdisciplinary evidence, in the tradition of William Gilbert (16).
