你的人生，他們六個說了算！

I'm curious whether personal experiences or scientific research drove the focus of this book. Did the author have a specific story or insight that sparked this exploration?

The explanations felt both enlightening and a little unexpected. I'm wondering if others felt more skeptical or more open to the ideas presented.

The book covers a range of substances, and I'm interested in hearing whether readers think some are more beneficial or risky than others based on the author's insights.
