This study indicates they (especially the eggs) can survive quite a while at 45

Your idea intrigued me, John, because it vaguely reminded me of
something I used to do. When I gave PHYS 101 lectures I would start off
asking the students if they wanted to be taught in metric only,
non-metric only, or a mixture of the two. They always chose metric only,

would find very few students would win any money at all on either set of
questions. In fact, many high school students would win no money, and even the
vast majority of those that did could not possibly do it without a

I would be interested in hearing some of your quibbles, as anything that
could improve the idea would be welcome.
I tried a UK version (metric the same, but the imperial s
That's a rather novel idea, John.
I won't mention my quibbles about the specific wording on some of your

There is a way to get the US predominantly metric in 10 years. It involves that
sure-fire way of making progress in anything - money and time.
The concept is quite simple, and consists of getting schoolchildren when they
are around 10 or 11 years old to make a simple choice: Embark on their
