I do a lot of biking. I need that mileage and the long-distance stuff because tennis demands it. My fitness trainer is always trying to convince me to do an Ironman. I can probably run the marathon, I can make the 112 miles on the bike, but I will never swim for 2.4 miles. I will die after 100 meters.

There probably could be some mileage in running a comparative study about how best to finance electoral campaigns around the world.

A Prius is not a true hybrid, really. The current Prius is, like, 2 percent electric. It's a gasoline car with slightly better mileage.

The hydrogen powered car, with its high fuel mileage and zero emission rate, is just one example of the products under development that will help increase our energy independence.

If anger were mileage, I'd be a very frequent flyer, right up there in First Class.
