        {}.tap do |results|
          results[:max_age] = Regexp.last_match[1] if value =~ /max-age=(\d+)/
          results[:includeSubDomains] = value.gsub(" ", "").scan(";includeSubDomains").any?

Split parse method into logical checks

```ruby
module Headlines

      def parse
        {
          max_age: max_age,
          includeSubDomains: include_subdomains?,
