This one is on me.

I'm getting old enough to experience my mother getting approached by pseudoscience health scam. Here is how my mother spent RM2310 behind my back.

The popular theory is that soft drinks are cheaper than water simply due to "marketing" that lets them sell worthless water. Indeed, a company can charge whatever they want and you just have to pay for it.

Why must it that water, of everything, has to worth more than soft drinks? It seems irrational that adding an extra feature (that is sugar and carbon) to a commodity (water) devalues it.

Few understand this.
