The word 'should' is pretty loaded. What you 'should' do is live in the
present and be happy. But if you're an economist you might think that you
should invest for the greatest happiness of you in the greatest number of
branches in the multiverse, which is what Deutsch implies. In all events,
you should invest for universes where you are alive, rather than dead,
unless you care about other people.
