You're right we shouldn't shoot this down in flames, but I think most of us would consider evidence with a sample size of one as un-evidence. Providing better evidence will not take a multi-million dollar RCT - all you'd need is ten ponds and a fortnight of checking them once a day. If that went well, you would have the confidence to push this harder, and maybe get a local university biology department involved to carry out a better designed study. And if that produced good results, you'd be ready to knock on the Gates Foundation door.
