It’s low IQ. Seriously, you can stop wondering right now. They have intellectual disabilities that usually go undiagnosed. Maybe because public schools no longer discriminate between kids with potential and kids without—they’re “integrated” and kids with low IQ are “mainstreamed.” Combine that with limitless calories available at any sugary slop dealer on any street corner. They literally can’t resist because they are so STUPID. That smile on that monster: that’s the bliss of chronic and incurable ignorance. Case in point: people with Down syndrome are about twice as likely to be overweight or obese.
