Rules learned through many years of traveling:
1. If you get upgraded to a first class seat, do not ever, under any circumstances, give up that seat for a coach seat on an earlier flight. The earlier flight will be so severely delayed that the flight crew will have put in too many hours and will have to go home, or it will be cancelled with no seats available on the later flight, or it will experience a mechanical problem so mysterious you will be transferred to another plane, whereupon the flight crew will have put in too many hours and will go home.
2. Go to the bathroom whenever you get the chance. For those of us with bladders the size of walnuts, this may just be the most important rule in the list.
2a. Corollary - If you need to use a bathroom and are on an upper floor of a building and will be leaving the building shortly (presumably at the ground floor level), do not descend to the ground floor to the use the bathroom, because that one will be closed for cleaning, or a water main rupture, or an infestation of some kind, and you will need to go back to the upper floor to use the restroom. If you do not return directly to the upper floor, the cleaning crew, water main repair people or exterminators will levitate to the upper floor and oocupy that restroom as well, thwarting your plans, and pushing you ever higher in the building to find a functional bathroom.
3. Eat a meal whenever you are offered one. You never know when you'll have the next chance to dine. See #1.
4. When obtaining directions to an unfamiliar location and the provider of directions makes a comment at the end of describing your route, which will include detours, streets that change names in mid-block, and buildings that "used to be there" as landmarks, that "you can't miss it", add an extra hour to your estimated time of arrival at your destination.

Exercise: Used the stairs every time I needed to get to my office today. Including the time the bathroom was closed on the first floor. See #2a.

Books: Moneyball keeps rolling along.

Music: Fleetwood Mac has had its second run. Enough already.

Movies: Charade and To Catch a Thief. It's Cary Grant night on AMC. He ate quiche in To Catch a Thief. Draw your own conclusions.

Cats: Xena misses having the warmth of the cable box to lie upon.

Dreams: Nope, though I did wake to the sound of another sky-opening drenching rain at 6:07 this morning.
