I think it is impressive he figured this out as a layman. This article is from one year ago, it would be interesting to see a response from some researchers. For example, have there been any studies to see if this method is valid?
Hmm seems he is a retired researcher, although it doesn't mention his background. The problem is it's quite a step up from anecdotal evidence from one guy, to doing any kind of trial involving volunteers, and it would need momentum and money behind it.
