You could do something like this:

class Person

  def initialize(opts = {})
    @options = opts
  end

  def my_age
    return @options[:age] if @options.has_key?(:age)
  end

end

and now you're able to call to the age like this

p1 = Person.new(:age => 24)

p2 = Person.new

p1.my_age # => 24

p2.my_age # => nil
