我們只有10%是人類：認識主宰你健康與快樂的90%細菌

The connection between microbes and happiness is fascinating but complex. I wonder what led to this focus and how much is still unknown.

Learning that 90% of what makes us 'human' is microbial was eye-opening. It makes me wonder what other assumptions about our bodies might be wrong.

The book presents a lot of cutting-edge research, but I'm curious about the process of selecting and interpreting these studies for a general audience.
