I was poor as a kid, so dentistry didn't happen until the toothache stuff didn't work any more, at which time it was pull it or fill it. By the time I was an adult (opinion, I realize
), I had a nice collection of fillings, and a few missing teeth. I recall that, in my forties or so, one dentist remarked that I had pulled that one out of the fire. The childhood history was obvious even though he could tell that all the mischief was much earlier, not recent.
Sadly, I don't float either, but I don't seem to have to work at it as hard as you do. If I try, the feet head south first, followed soon by my head. Maybe in the Dead Sea things would be different.
