I have seen grotesquely-obese people in their 30s and 40s navigating their way on carts in Wal*Mart. Such people are effectively disabled. I can't imagine anyone willingly eating himself into such a condition.
Death wish?
How about an effective system put into place by the ultra wealthy elites that encourages people to eat low price unhealthy foods that have addictive qualities to them? And yes I'm including those elites that pay lip service to "supporting the poor and middle class" while also supporting policies that have destroyed them while also promoting policies that support the ultra-conglomerates.
