Wear Your Seatbelt

Seatbelts protect you. Always wear one when you're traveling in a car, even if only for a short distance. You may sometimes hear some anecdote about someone surviving a car accident who was not wearing a seatbelt, and some authority saying that the person would have died if the seatbelt was worn. Well, if that's ever really true, it is extremely rare compared to lives and functionality preserved by seatbelts.

Why don't they make cars that only start if the driver's seatbelt is buckled? If fact, cars now have sensors that deactivate the passenger airbag when there is no passenger. That same sensor could prevent a car from starting if a passenger isn't buckled in, too. Sure, someone could still buckle the seatbelt and sit on top of it, but that could be made uncomfortable, and I bet that the measure would still be a helpful nudge.

Don't Tailgate

I had always been told that you should stay a car's length away from the car in front of you for every 10 mph. That seems like a good rule of thumb. I see all kinds of nonsense on the road, though. There is no excuse for foolishly driving too close to the car in front of you. If the car before you has to brake for any reason, you will collide. You will not get to your destination any sooner by tailgating. I have seen a lot of collisions that would not have happened if the back driver had let there be more space between the cars. Use reason when you drive. Keep your distance.

Eat Little White Flour

Don't eat much white flour. It pumps the blood full of glucose too quickly, and it leaves the bowels too slowly. It doesn't take long to acquire the taste for whole grains.
