Heavy consumption of the essential amino acid lysine (as indicated in the treatment of cold sores) has allegedly shown false positives in some and was cited by American shotputter C. J. Hunter as the reason for his positive test, though in 2004 he admitted to a federal grand jury that he had injected nandrolone.  A possible cause of incorrect urine test results is the presence of metabolites from other AAS, though modern urinalysis can usually determine the exact AAS used by analyzing the ratio of the two remaining nandrolone metabolites. As a result of the numerous overturned verdicts, the testing procedure was reviewed by UK Sport . On October 5, 2007, three-time Olympic gold medalist for track and field Marion Jones admitted to use of the drug, and was sentenced to six months in jail for lying to a federal grand jury in 2000. 
Handcraft more than ever is a strong direction for the future. Since the two past decades, we have seen an increasing interest in handmade; first to rediscover nearly forgotten shapes and techniques, to associate these manmade objects with industrial ones, then to inspire serial productions with a handmade twist and now, more and more, to map a new road for creation taking into account not only local talents yet also local and sustainable production. A new way to look at history of man and to rethink ancestral knowledge in order to shape rooted, human and smart design for the future.
