Not my point, though, which is that the way MWI is usually presented, 
it's many *orthogonal presents* that contribute 
to/constitute/comprise the observed reality. Therefore it seems to me 
improper to peel off one of these superposed alternatives and say, 
"Hey, that's the one I'm living in!" If that were possible, we should 
be seeing lots of events that *don't* follow least energy 
trajectories (which are always a composite). Unless, of course, we 
do, but the macro-scale of what we usually observe is a statistical 
blur of such weird dog leg tracks. But that's not what I read in 
Feynman, say. What you see is what *every* "you" gets, all nicely cohered.
