Great post, modded up. I have a question, since you seem to be rather conversant with aging research. I am a physicist, and I'm interested in how mitochondrial function is measured and the efficiency is defined. I know that it is measured via oxygen consumption rates, but all the papers that I have read do not define precisely how this is measured and defined. Would you kind enough to point me to some resources on this? I am capable at reading the medical/biology literature, but searching it can be a different matter.
