Spa treatment?

I really am no judge. I don't know if the latest bin Laden video shows a much healthier individual than his last taped message, where, according to the NYT's Jehl and Johnston, he "appeared gaunt and somewhat halting as he picked his way along a trail with a walking stick."

But if that is true and he has recovered his health (though as Josh Marshall points out, he still looks older than his 47 years), then how -- and where -- has he been able to do that? He had been described as being practically on death's door, requiring sophisticated medical devices, or so I was told.
