Well, there is one other thing he can't fix: His height (aside from catastrophic changes)

The man is 6'5" or something, and that would be something difficult to change.

Shave, khakis and a blue shirt, gain 80 pounds, and 6'5" wouldn't give him away.

I had forgotten about that. It is a good point.

If he is still alive, he could minimize the height problem by "hiding" in a wheelchair (he may even need one). There are a lot of people in his territory - be it Iran or the Afghan/Pakistan border, who are not blessed with full mobility.

Among wheelchair users, he would still be tall, but he wouldn't stand out like he would at 6'5".
