I think he already has diabetes, but is engaging in the same bad habits as Pa, ie. drinking alcohol and eating richly.
I saw evidence re: this fat bastard day before yesterday on Pyongyang TV, "inspecting the troops, on the spot guidance". Might be trying to get him up to Kim Il Sung class wrestling weight class. Without sanctions, Burger King could do a good business up there perhaps, feeding the fat pig.
Thanks, I was not up to speed on his health.
