Or, take fewer showers. You don't need to shower every day in winter, do you?
Would that be showers taken with reduced water pressure? Or do you perhaps mean fewer showers?
Some might say that my going on about "less/fewer" and other similar grammatical arcana is unfair or irrelevant. There is some merit to that argument, but we're comfortable tearing people's computer code apart, and this is a similar activity -- except in an emotional sense. Most people who eagerly welcome computer code corrections bristle at grammatical corrections.
So thanks for taking my comment in good humor.
