I don’t think I buy the diet thing at all.
In the US, it’s commonplace for people to “get a tan” and people in general are not as protective over sun with the use of sunscreen or long sleeves/pants.
In many Asian countries, whiter skin is more desirable. People are a lot more diligent in wearing long sleeves and pants when spending time in the sun and etc.
The sun will age you a LOT.









What I’m getting at is these large plastic jugs of water are not just purchased routinely by the majority of the population when grocery shopping.
