Others may be able to multi-task in such situations. However, SA is  a mere mortal and is having to take a break from illuminating the dark underside of archaeology. I’m the PI on a long-overdue project to investigate the deeply stratified site that comprises the kitchen sink and laundry hamper. From the look of it, I’ll need to use shoring, which as you all know will almost certainly prolong the excavation. Be back soon.
