I disagree with his graph showing how hearing degrades with age. And that he states that if you trust a reviewer who is older than you, you are a fool.
Everyone is different, some have great hearing that lasts a long time, others probably stick closer to that graph. But, the author is making a ganeral statement that if someone is older than you, they have worse hearing than you.
