In this post, I'm referring to the practicality of being naked. Last weekend I pressure washed and bleached the patio, worked on the pool, and did some major yard work in the back yard. Our fence offered adequate privacy, so I worked naked most of the two days it took me to do all that.
The practically of working that way was wonderful. Those were dirty jobs that would normally have left me sweaty, wet, and dirty for long periods of time. Instead, I could simply rinse myself off whenever I wanted to and air dried as I continued to work. When I spilled something caustic on myself, which happened a few times, I realized it right away and could rinse it off, rather than have it soak into my clothes and have to go change after I finally noticed.
Any hot, wet, dirty or grimy job is more comfortably done naked as long as it's warm enough where you're working (rarely a problem here in Florida).
On vacation a couple of months ago, I talked my wife into spending a down day and staying overnight at a distant nudist club along the way. I guy came into the clubhouse covered in grease from head to toe from working on a bus he was fixing. My wife still thinks of clothing as protective in those circumstances, where I just see it as making things worse by getting soaked with whatever you're working with, then grinding it against you for the rest of the day.
