I honestly don't think she thought that out very well; she just made it easy for her family & friends to remember, but it also made it easy for Jo Public to find her too. I don't think on her own she's intuitively clever, I don't get that impression from her videos. Experienced on YT after so many years, yes. Experienced shopper, yes. Experienced taster of other people's food: yes. Experienced matcher of greys to blues and whites in home decor and Christmas themes, definitely. But, I am not thinking of Tiffany as an astute critical thinker.
I don't think she's ever described the surgery details has she? Has she ever used the terminology "PE", or is it just knowledgeable subs who offered the terminology of what would be involved?
Sadly, I don't think Tiffany's channel has ever been steeped with a deep understanding of the medical journey she's been on. If she has a better understanding, she has not shared it with her supporters beyond the superficial details as well as a much deeper exploration into the physical facades, the hallways she walks down and the waiting rooms she sits in.
