[must make at least one postaday....]
(what if tsuwm had been reading about autophagy too? what if he beat me to it, again?
oh wait - he would have known the word and simply continued reading).

well, actually®, I would have had a slight pause whilst saying to bahself: autophagy? must be eating oneself [yuk]; based on having lots of -phagy in my past; e.g.,
oligophagous - eating only a few specific kinds of food
pantophagous - eating or requiring a variety of foods
scatophagous - habitually feeding on dung: coprophagous
