    > notebooks are hard to sterilize

Washing / sterilizing the lab coat has the same effect as erasing the data written on it.

There isn't a library of lab coats which contain notes written on them, for future consultation.

A notepad page is also easier to permanently sterilize (via incineration) than a lab coat.

		The labcoat is a kind of L1 data cache.
