              <p>This assumes that extreme longevity will reduce the
                desire to have children, which seems a reasonable
                assumption, given the usual real reason for having kids
                (to look after you in your dotage). Note the extreme
                difference between having an average of 2.5 kids and 2.
                Note also that 2 kids per couple is no longer
                'replacement rate', as there is no death. Of course
                there still would be, but from accidents etc., not from
                ageing.</p>

        <div>True, the usual reason would go away - but with no death,
          people with other reasons would have a lot longer to have and
          raise kids.</div>

    <p>Ok. So how much would that affect things? Would it negate the
      benefits of life-extension?</p>
    <p>I realise we don't know the answer to that, but is it a reason to
      say "No, let's not bother with life-extension, it won't help"?<br>
