Share My Creation It Is Finally Time to Fix Your Health and Fitness

I have written a book on health and fitness. It is available here: There are also some supplemental videos for the book here: I position this book as an antidote to the health and fitness industry. I wish I had read it 20 years ago. I strongly recommend you not wait 20 years to read it.

At the first link, you'll see that the ebook is only $4. The first 1.5 chapters are provided as a free sample. The book's description will give you a flavor for the book's goals.

What does this have to do with B4X?
  • The research data collected for the book was done with programs I wrote in B4A and B4J.
  • The data was analyzed with programs I wrote in B4J.
  • The graphics were created in programs I wrote in B4J.
  • As was the book cover.
  • The videos were edited in a video editor I wrote in B4J.
The first commenter who can correctly identify the interesting mathematical problem I had to solve in order to create the book's cover gets 10 points. And the first commenter who can identify the solution to that problem gets 10,000 points.

Yes, the interesting math problem has to do with generating that effect. But it's not the recursion that was a problem. You're on the right track.
