Thought experiment: Suppose that someone has never experienced touching hot objects
before. As long as this person does not find out that touching hot objects is painful,
either by touching hot objects himself or by being told that it is painful, he will be
in a superposition of two sectors of the multiverse where he has and has not the ability
to feel extreme pain when touching very hot objects.
The sector where he does not have the ability to feel pain has a very small amplitude,
there evolution has run a different course. In the other sector evoluton has run the
course where the ancestors in the first sector ddidn't survive, it where the creatures
with some mutation that lead to them feeling pain when touching hot objects that
survived here.
The mere act of touching a hot object is a measuremnt which locates the person in the
latter sector, only then does the outcome of the events that happened a long time ago
become determined.
That assumes that the "same person" exists up to the moment of measurement, differing, via
FPI, only in the ability to feel pain. I doubt that is possible. There is a common
assumption that QM makes anything possible, but it actually imposes some restrictions,
although it's hard to say how they extend to the biology of macroscopic beings.
