I think the problem with these kind of experiences re: the physical effects, is that it’s subjective, and people just aren’t omniscient. Many people are often fooled themselves by variables as simple as angles, lighting, for example. I’ve known people who had bad skin, look in a mirror under certain light conditions and truly believe their skin was suddenly in better condition.
The reality as an outside observer who could view the skin, was that nothing had really changed. You can really see everything under light conditions such as full, direct sunlight.
This isn’t to say what OP experienced isn’t true, or that wearing gold can’t have a physiological effect, but more in response to what this thread has become. Whilst I believe change can be quick and happen within a day, it isn’t nonsensical to think that someone may be fooled into seeing such changes because of other variables. Yes, they really do see a difference, but is there an actual difference?
Healthy skepticism (even in regards to your own personal experience) and objective evidence is a necessity, imo. Separating the wheat from the chaff, so to speak. There have been plenty of times I’ve had an experience and was sure that x and y was the cause, only to discover later that that was far from the truth.
To put blind faith into an experience just because it’s an “experience” is just as bad as denouncing an experience like everyone is jumping on Jing for, imo.
