&gt; How then do we deal with population growth when people don&#x27;t die of old age?<p>That&#x27;s not nearly as much of a problem as people think it would be.<p>About 60 million people die per year, and about two-thirds of that comes from age-related causes.<p>Something like 75 million babies are born each year, and that number is gradually but constantly shrinking as standards of living rise and people have fewer children.<p>The most likely result in a world of reliable anti-aging treatments would be a gradual slowing of new births to a trickle long before the reduced death rate ever became a real logistical problem.
