A4 waist challenge: The thinner, the better?

This is downright stupid and sad. Everyone needs to just try to be a little bit healthier and exercise more, and then embrace the different sizes and shapes from there. Stop trying to compare different women to each other, because the human body can be different shapes and sizes dependent on a variety of reasons, including nationality, height, body type, etc. Health is what is important.
