So the temporal relationship is much is much broader as opposed to like you know we can measure a lot of these things by just checking serum levels which we do like CRP looking at inflammation or glutathione levels to try to get a sense of reactive oxygen species but that is like a single time point that can change over a matter of hours whereas it's when we look at sperm or or bone mineral density we're looking at a much longer time point of months to really like sometimes even years of your overall health. So it gives us such a longer tale to look at to understand how you're living your life on a regular basis. That's cool. So compounded gains that like the things you have to do they accumulate and this is true with with uh but yeah bone middle density is like your skeleton rebuilds itself every 10 years.
