Thank you for that thorough explanation. In my family, we have a rather uncommon incidence of autoimmune diseases--a couple that are rather rare. Not all of these were expressed later in life, but several were. It's always fascinated me how our friend (the immune system) becomes our enemy, and sometimes ferociously.

I will be rereading your response slowly and carefully so I understand more.

I love this line

Since we know mitochondria gets fucked up in ageing

Thanks for that:)

I enjoy your blogs. They are science, but I sense in them a tinge of compassion for those who are affected by the hard reality of science.
