Using NMRMS based metabonomics and targeted lipidomics approaches the inventors have explored the metabolic phenotypes of aging and longevity in a cohort compromising centenarians, elderly and young adults. The platform members are attached to each other along one or more surfaces and are capable of being disassembled into smaller components. This device includes an input gear 11, an output gear 12 and a switch mechanism 13. The invention also concerns a timepiece mechanism incorporating at least one pair of opposing components, one of which drives the other or is supported thereby, said pair being made or transformed by implementing this method. A processalgorithm is described and, unlike conventional algorithms for detecting tissues and cells, may allow for zero false-positive fluid identifications across a plurality of samples.
