Satire of your comments aside, the flips side of this is accepting obesity will see it get even more of an issue than today.
What does piss me off if vanity sizing. In the past 10 years, I have gone from a Medium, to Small, to now sometimes even XS or XXS. Even though my body shape hasn't changed at all.
Even waist sizes are fucked. 30" should be thirty inches, not just another arbitrary size. I often have to find 28" waist jeans, to fit my 30" waist.
Life is tough.
