I think it's called "FAT"... was very hard to observe until recently when the ENTIRE WORLD got F.A.T. off of bad diets, too much sugar and complete apathy toward exercise...
Seems odd to me - there are books and papers written on the same subject using the same terms that are easily found dating back to the 1980's, even Wikipedia references ! - so its hardly new knowledge.
Maybe its just the new claim of being an organ ?
