Bart's hands twist together, fidgeting now that he's not handling anything. "In my time it was common for there not to be many collaborators on these decisions when it came time to actually perform the necessary surgeries. There were automated methods that only required someone to be there to oversee. I've been having to learn all of it from scratch, more or less. A biologist shouldn't be a doctor but the principles of the former can be applied to the latter, obviously. That, and the common sense measures of my era are far beyond what the general population here is up to date on, so I've got the leg up that means it can be applied to others' education. Doctor Watson has been able to avail himself of my notes and ask questions, though I haven't been able to tell him everything I can remember. I don't want to give him any information in error without checking with others."
