The effects of have clones is interesting, though, regardless of the
"sapping strength" notion.  You would have reason to worry about being
killed if there were clones and then a "shell game" was played with
you being mixed up with the clones, and then all of the "yous" were
killed except one.  All of the "yous" would have reason to worry.
This has implications on ethics of cloning and killing clones.
As far as measure, it seems that having a clone of you and killing one
of you while you were asleep would be equivalent (w.r.t how much you
should worry at least) to not having any clones and someone saying
they were going to roll a die and if it came up odd they would kill
