Protect yourself the old-fashioned way: Become a compulsive hand-washer. A recent Naval Health Research Center study found that when recruits washed their hands at least five times a day, they had 45 percent fewer respiratory illnesses, such as infection by the flu virus.
"Vaccination is the best preventive measure, but hand washing is a good alternative," says Dr. Carolyn Bridges, a medical epidemiologist with the Centers for Disease Control and Prevention. And yes, regular soap will do the job; antibacterial cleansers aren't any more effective against viruses.
Try sweeping your honey off her feet with a quickie. Lead her into the bedroom 15 minutes before you both have to head out to work. Or drop by the bathroom just before she steps into the shower, lay a towel down on the floor, and get dirty.
"The spontaneity is a definite turn-on. It's nice to think someone wants you so badly that they can't wait one more minute," says Tara Roth Madden, author of Romance on the Run: 5 Minutes of Quality Sex for Busy Couples.
Just be careful not to pull the ravish-the-maiden bit too often, or she'll think (rightly) that you're an unromantic bum who just wants to get off.
Skip the black-five-sugars coffee and pop some NADH, a coenzyme that may increase mental alertness and concentration. In one New York-Presbyterian Hospital study, researchers tested 25 sleep-deprived people after the group had taken 20 milligrams of NADH and then again after they'd taken a placebo.
"When the people took NADH, they performed significantly better overall on a set of mental tests using a measure of speed and accuracy," says Margaret Moline, Ph.D., one of the study researchers.
Look for supplements that say "ENADA" on the label; they contain the same NADH formulation used in studies.

Hit the hardware store and pick up a refrigerator thermometer (about $10). Here's the logic: A crumb here or a drip there (okay, numerous crumbs and drips) won't hurt you as long as the temp is low enough to prevent bacteria and mold from turning your fridge into a greenhouse. "If you do nothing else, make sure the temperature always stays below 40 degrees," says Don Schaffner, Ph.D., a food-safety expert at Rutgers University.
But why the retrofit? Because many refrigerators don't come with their own thermometers, and even with those that do, there's a good chance they're off by a few critical degrees. Note: You can stick your thermometer anywhere but on the inside of the fridge door; odds are this spot is a few degrees warmer than the rest of your icebox.
Toss everything in the washer, dump in some detergent, choose "Permanent Press" and "Warm," then walk away with a clear conscience. According to Brett Oleson, a senior consumer scientist at Maytag Appliances, your whites will come out clean, and your colors won't fade.
