how difficult a bridge is that I'll tell you about uh two steps we're taking uh one of them is a collaboration with Steven Cummings and Teresa Mau and their colleagues they have a project at UCSF called Som s so they have a collection of several hundred human volunteers all in their 70s in good health these people took a lot of functional tests how good are they at thinking how fast are they how strong are they and then they allowed tiny tiny muscle biopsies and Tiny fat biopsies so we have requested and I think are likely to receive tiny bits of muscle and fat from these Brave volunteers and we will test do those that have a lot of the muscle specific change which is a protein called fndc5 and the fat specific change like ucp1 for instance our prediction is that amongst the 7-year-olds the really fit ones will be the ones that look as though they have always had uh youthful aging rate indicators so that will be one way in humans and we'll have plasma from these same people as well so that will be one way in humans of beginning to test internal tissues to compare with plasma but that's impractical for clinical use
