Some mechanic told me this business about batteries and concrete. It
sounded good to me even though he ain't no physikist, either. When I was
a carpenter (not Karen), I was told that sitting on concrete for any length
of time would automatically cause hemorrhoids. I don't believe this, but
I haven't been willing to disprove it. Soon, I'll be throwing salt over
my shoulder.
I have some good batteries sitting around in cars that I'm not driving, so
I'll set one on concrete and see how long it takes it to go dead. And I'll
do this about the time I remember to call the guy who told the alternate
MOWOG story. In the furor after I accused Cecil Kimber of being a doodler,
no one answered my question: has anyone ever seen MOWOG on a pre-war part?

Naaah. I could never hate _you_.
BTW, a chain is ten yards so they know if it's a first down or not. Any
Brit who wants this explained will have to explain cricket to me. And
while I'm on the subject, since the British invented the measurement
system we use, how come all of _their_ measurements are bigger?
