I think Parfit is saying that we only have psychological continuity unless your brain is split into 2 than you become 2 people and it becomes complicated.
Or am I wrong and is he a bundle theorist?
There is no continuity except for the body. We have memories which are a sort of continuity, but that is about it.
The continuity depends on the scale you want to look at.
