We use an argument by Page to exhibit a paradox in the global description ofthe multiverse: the overwhelming majority of observers arise from quantumfluctuations and not by conventional evolution. Unless we are extremelyatypical, this contradicts observation. The paradox does not arise in the localdescription of the multiverse, but similar arguments yield interestingconstraints on the maximum lifetime of metastable vacua.Comment: 8 pages, 1 figur
