Anderson made a passing remark to not being able to take "the standard anti-ageing pills" 
, which some readers interpret as meaning anti-ageing drugs are issued as standard ... rather than Anderson saying she can't take just any old anti-ageing drugs.
Even if you're wedded to that interpretation of that one
