Dr Li you need to read your transcripts to see how hard it is to follow you and what you are saying. Forty-five minutes and I walk away not knowing what to eat to fix hair loss. Mushrooms, tomatoes, orange peels. I think I got that right. You say so much and yet say so little. This was a topic I really wanted to know about and I feel like all you wanted to do was keep us guessing so we buy your book. But I worry that the book will be the same ramblings that your manuscripts show.. I think we have a lot to learn from your vast knowledge but you have to tell it in a better way. With way less distractions.
