I think there was a slight misunderstanding. Sol didn't say he does his own teeth, he said people could do it. Quote from another thread, click link to see it in context:
you must be one of the lucky ones to have been born with good teeth and lower incidence of plaque buildup
You don't need a dental degree to scrape plaque. This is something you can do at home with tools you can buy at Walgreens.
This is like people who include a line item in their budget for haircuts. Okay sure, you could pay someone to do that for you...
Wait, scraping plaques counts as cleaning your teeth? How about flossing? Dentists will do that for you too, you know.
I do brush my teeth, and I floss, and yes I have scraped plaque off of my teeth before. These are not the reasons I go to the dentist. These are basic home dental care. Dentists provide specialized services that I can not perform at home. Basic cleaning is not one of them.
Sol, I would love to see your haircut. I bet it is really beautiful.
I was bald for a while, and I never paid anyone to shave my head for me. You can, if you like.
Now I have a job where hair is beneficial, so I'm not bald anymore. But most men's haircuts are reasonably easy to learn to do, though not to yourself. My wife does a wonderful job with it, and we've asked enough people to critique her work that I'm comfortable asserting that it is indistinguishable from what a barber would do. The only down side is that she takes about twice as long to do it, but then again I'm not wasting time driving to the barber and back or waiting for a chair to open up, so I feel like the time trade off is about even. On the bright side, I basically only get haircuts after about 9pm anymore, which is more convenient for everyone.
But this forum has strayed a loooong way from the days when people used to post about re-using paper towels and cutting their partner's hair. Once upon a time, this place was about self reliance and frugality and environmental protection, not $600 blenders. Which is, after all, the thread we're currently in and the very reason why you're attacking me for not wasting money.
But hey, if making fun my wife's haircutting ability, or my imagined appearance, is what you need to do to feel better about your Vitamix, you go right ahead. It's no skin off my nose. I think you're confused, though.
