That is exactly how I intended it to work. >:-)

And exactly my current attitude. I've conserved quite a bit for my life, it makes sense to do so since energy costs money and a penny saved is a penny earned. If this is such a dire emergency- then it's time for those gulfstream liberals to stop flying.

More like- if the drought is real, then no bathing should be justified under any circumstances. Bathing can only be justified if the drought is false (that is, if we have the water necessary to bathe).

In other words, more a matter of conservation in time of emergency. If the emergency does not exist, then continue as normal.

The cytosine methylation signal along a strand of DNA is theoretically heritable, even though it has nothing to do with the actual sequence of bases.

There are vast stretches of junk DNA in the genome, some with old genes for ancient viruses or parasitic sequences like transposons, and the way the cell keeps those parts of DNA away from cell machinery is by methylating the cytosine residues. The methyl groups prevent RNA polymerase from transcribing the DNA and therefore it gets silenced.

When a cell divides, the methyl groups are only on the original strand; the new complimentary strand doesn't have any. The methylation signal has to be actively transcribed from one strand to another; an enzyme runs up the DNA feeling for methylated cytosine residues. When it finds some, it starts methylating any cytosine residues that might be nearby on the opposite strand, to make sure the troublesome regions all stay commented out. That's why it's heritable.
