Nice book

I like your book - just 1 thing I would like to suggest - that Floride is toxic and should not be used in tooth paste or water etc...

I moticed the google ads - It looks like a great union. People get free content and if they click through and buy something you get something.. well I suspect that is how it works...

If you would share - how to set up a educational book as you did?

Thanks
