Ephron speculates on Bush's emotional health

From Nora Ephron's post on The Huffington Post:

The point is that it seems possible to me that when George Bush gave up alcohol in 1986, he dealt with the depression that often accompanies sobriety by becoming an obsessive exerciser. And that's what he's essentially done ever since. He's never held anything that could be confused with a job. Owning a basesball team is not a job. Even being governor of Texas takes only a couple of months a year, it turns out. So he was free to exercise.

But at some point this year, something happened and the exercise regimen stopped working. Bush started becoming depressed. My theory is that a certain amount of panic ensued, and more exercise was prescribed: hence, the afternoon on the bicycle in Maryland, and the reluctance to disturb an already disturbed, irritable man. (Interestingly, the incident happened just after the President returned from a four-day trip to Europe, which had not only required him to work several hours each day but undoubtedly interrupted his exercise routine.) Then came the vacation in August, the odd, sequestered vacation, a perfect time for the President's doctor to try medication, or change medication, or adjust medication. Then Katrina and the emergence in the fall of an unenergetic, irritable, muted, unfocussed President, the man you see today.

Bush still has three years to confirm or disconfirm this speculation.
