OTOH, people our age produce ever-diminishing quantities of stomach acid,
which is necessary to absorb B12. Thus as we age our B12 drops off, often
way off by retirement age. The bad side, even if B12 is detrimental ? Our
nervous system NEEDS B12. Its lack often causes irreversible nerve damage,
even more noticeable at our age because we've lost 40% of our nerves by age
60 anyway. With less stomach acid, we can't get enough B12 from diet or
pills (it's tough to get enough from unsupplemented food anyway, so the
choices are injections or sublingual (under the tongue) pills.

PC takes many years, more like decades, to grow. Lack of B12 can harm nerves
much more quickly. I've been taking sublingual B12 for a couple of years,
and will keep doing so. One reason is that I'm sick of all this knowledge
burning holes in our screens and brains. Right now, today, we have
conflicting advice on scores of nutrients, and that's just the "proven",
mainstream, Johns-Hopkins/Mayo/NEJM kind of proof. The BS flooding the
internet and bookstores merely compounds the REAL conflicts a thousandfold.
The legitimate contradictions alone will increase exponentially with medical
knowledge in general, and will expand to devour our waking hours if we let
it. Look at what the low-carb BS alone has done not only to its obsessive
victims' waking moments (and cardiovascular systems) and to several whole
industries. Thank goodness people are starting to see through it and it's on
the decline.

B12 MAY promote cancer. Its lack DOES harm our nervous systems, and much
more quickly. And we can find legitimate conflicting demands in dang near
everything we eat, so why drive ourselves nuts over it? KISS, eat a wide
variety of healthy foods, avoid a few like the plague (because, like sat
fats, they will sneak through our guard anyway, and we need small quantities
of even the worst offenders -- except trans fats), and enjoy your food
rather than fear it . . . ribs and bacon and chicken skin and commercial
junk food notwithstanding.

Maybe in another decade "they" will enlighten us with "the word" on whether
B12 is good or bad overall for people with both prostates and nervous
systems. Of course, by then they will also know of 5 more good and bad sides
to it and to each of the other few hundred foremost nutrients in our diet.

I don't have the free time to worry about that many details. Do you? I mean,
hell, some of us still SMOKE, let alone eat Oreo cookies and drive fast.
