Well, I am very uncomfortable by the fact that apparently in Singapore (Asian context), many flock to the section of "Feng Sui" / astrology / palm reading / fortune telling stuff/ homeopathy. Which for me is categorized under Pseudo science. It is scary that a large number of the population would "devote" their lives to faithfully reading this crap. (Excuse my french...)
Feng sui -
How do you actually define energy flow in the body. Yin ang yang ?
Pertaining to horoscope/astrology -
"You participate in the mass cultural delusion that the sun's apparent position relatively arbitrary define constellations the time of your birth somehow affects your personality." - Sheldon. (The big bang theory)
Palm reading/fortune telling -
It's probably cold reading and a bit of neuro linguistic persuasion that leads you to believing that the gibberish the guy is taking about is actually true.
Homeopathy -
ear candling - there isn't a vacuum and the yellowish stuff you see is not ear wax !
Fish nibbling on your wounds - more a medium for communicable diseases.
Bubble baths for your foot that apparently turns brown due to the release of your body's toxins and bad energy - its a chemical process, somewhat like rusting of Fe ! and Chlorine gas gets released. Next time try not putting your feet in, I'm quite certain the water will also turn brown.
