What people should look for is a well preserved meme.

Fasting is a very, very well preserved meme - across broad geography and many different ethnic and religious groups.

That means something. Regardless of whether or not we understand the science of it, or how we feel about "the messenger" (in this case, religious teachings that we may or may not harbor animosity towards), a very well preserved meme is worthy of our attention.

Is it true ? I don't know. It's interesting, though, and is worthy of our attention.
