Let's do a little survey.
If you look at this nude picture of the model GG, does she seem "worryingly thin" to you?
Apparently it does to several people. Which puzzles me, because while she is clearly very slender, she also seems to me to be obviously healthy (even very healthy), and not pathologically thin in any way. I asked Pascal, who is a doctor, and he has the same opinion. But then he asked an older family member, who has the first opinion. So I decided to do a little informal survey, just to see if we can shed a little light on this puzzling diversion of opinions.
I am suspecting an emotional over-reaction here. For decades fashion models got thinner and thinner, and now there's a strong reaction against it which goes a bit too far.
