one of the winter swimmers didn't have any brown fat when we measured him zero zero and uh in we do see this um in in in previous studies as well that some humans don't have any brown fat was he did he carry a lot of white fat atopus tissue was he was he obese no he wasn't no he was not obese because that he would not have been in the study then oh right yes you mentioned this earlier forgive me no no fine but he was um but what I did observe before knew that he didn't have any Browner was that during the cooling experiment where I cooled them for uh 2 hours before they go into the Pet City scanner uh he was not able to control his shivering like the winter swimmers could so he got he got very uh cold very easily compared to the others
