You can iterate through them all if you really need it:

    people_array.to_a.map{ |a| a.map(&:to_s) }

But, I don't see any point to do so, as for example if you want
stringify this Hash - all symbols will automatically become strings and
so on. Also if you'll need to output this as a list:

    people_array.to_a.each do |pair|
      name, age =3D pair
      puts "#{name} is #{age} years old"
    end


*Disclaimer: the code above demonstrates work with symbols, not
             iterating through Hash or Array
