So you are using Blue Chas as a way to determine the SES status of the person is it? Pls lah, there are people who never declare their income and also got this card if they apply. In the official govt data, they are unemployed but in real life it is a diff matter.
It is to give discount when you visit dentist and doctor. If you use it, it means you didn't know the way to take care of your health properly.
i never visit local dentist for cleaning after the pandemic or go to any dentist for any regular cleaning, basically zero cleaning. I floss daily using unflavored floss and use non-fluoride toothpaste currently using baking soda toothpaste. i never see doctors at all as i dun take and rebel against big pharma. my natural doctors are sunshine, exercise, organic food and drinks, filtered drinking water, less or no stress, be happy ( women-free life contribute a lot to it)
