I live alone, spending most of my days writing and blogging and I very rarely have to interact with other people. After my daughter went to college and I was back in my writer hermit mode, I began wondering if there was a point to a daily shower. Even at "quick guy shower" length one is wasting precious time that could be spent with Netflix, after all. Absent the need to make other people happy, was there any sound reasoning for wasting water like that?

Not really. In fact, not only is frequent showering not necessary, it can be harmful to the skin:

Anytime you take a shower -- especially a hot one -- with soap and a scrubbing device like a washcloth or a loofah, you're undermining the integrity of your skin's horny layer. The soap and the hot water dissolve the lipids in the skin and scrubbing only hastens the process. The more showers you take, the more frequently this damage takes place and the less time your skin has to repair itself through natural oil production. What's more, the horny layer of your skin can be sloughed off by scrubbing, exposing the delicate skin cells beneath. The result of showering too frequently is generally dry, irritated and cracked skin.
