STUDY FINDS HEAVIER OLDER PEOPLE ARE HEALTHIER

JUNK FOOD SCIENCE - Dr. Yutaka Takata and colleagues from Kyushu Dental
College in Kitakyushu City in Japan, examined 697 elderly, 80-year olds
from rural, suburban and urban communities across Japan (this
representative sample was more than half of the entire population of 80
year olds in 9 locations). After administering complete physicals,
including laboratory tests, and weights and heights measured by medical
professionals, the participants were followed for 4 years. There was no
loss in follow-up, meaning they knew exactly what happened to each of
the study participants. During the four-year follow-up period, 107 died.
Within this cohort:

- Overall mortality was 3.95 times as high among those who'd been thin
(BMI less than 18.5) compared to fat people ("overweight" and "obese")
and 2 times as high than "normal" weight (BMI 18.5 - 24.9) people.

- Cardiovascular disease deaths were 3.45 times as high among the thin
people compared to "normal" weight or fat people.

?? Deaths from pneumonia were 3.59 and 3 times as high among the thin
and "normal" weight people, respectively, compared to the fat people.

- And cancer mortalities were 17.69 times as high among the thin people
and 7.64 times as high among "normal" weight people compared to fat
people.

And lest you think these associations were because the thinner people
were sick or something, the researchers said these associations were
after adjusting for gender, smoking status, drinking, any weight loss in
the past year, blood pressure, physical activity, marital status,
preexisting disease, residence, and serum cholesterol and glucose.

In other words, said the researchers, being fat was consistently
associated with longevity and a lower overall risk of dying from any
cause, including cancer and heart disease - three times lower than thin
people and two times lower than "normal" weight people. It would seem
the natural weight gain with aging is beneficial. Regardless of beliefs
that overweight people are at higher risks of getting cancers and heart
disease, that didn't play out in what people actually died from.

Overweight status in elderly is associated with longevity, the
researchers concluded. "The lower mortality found in overweight
individuals seems to be associated with lower mortality from
cardiovascular disease and cancer," they said.

If such stunningly higher risks of dying had been found among fat
people, compared to those who are slim or a "healthy" weight, the news
would no doubt be plastered across the media. But it's the opposite, and
the media is characteristically demure when reporting any favorable news
about fat people.

THE COPULATIVE BEHAVIOR OF LADYBUGS

ANDERS RASMUSSEN, DENMARK - To describe the copulative behavior of a
ladybird, or a coccinellidae as it is called among scientists, is
actually quite hard due to the fact that the category contains at least
5000 different species. The account that I will give here perhaps only
applies to a fraction of the 5000 different species, but it is
nevertheless a fascinating type behavior.

So imagine that you are a female ladybird. Because you are already four
days old you feel it is really about time that you get a hold of
yourself and cease to live your life in an aimless fashion. You feel
that it is time to get pregnant. While wandering about on your green
plant reflecting on where your life has gone you suddenly look up and
see an attractive male about 2 cm ahead (which is about how far a
ladybird can see). You feel really flattered when this handsome stud
mounts you, but then, when he is just about to insert his thing you
instinctively start to run around, kicking forcefully backwards to get
him off. This stud won't give up that easily though so in spite of the
rather uncomfortable ride he hangs on. You therefore switch to a
different strategy. Almost to your own amazement you throw yourself off
the green plant and fall towards the ground. You make your handsome stud
land first thus making him absorb the long fall. For a second the male
lets go of you and you try to escape, but luckily for the male he
retains his consciousness before you have been able to run more than 2
cm away in which case he would not have been able to find you.

The stud mounts again and this time you don't fight. Instead you think
to yourself, this guy can copulate right after falling down an
equivalent of ten floors, now that is a trait I want my ladybird
offspring to have. So the romance begins, and since you are ladybirds,
and since ladybirds are fond of copulating you go on for a long time.

If both the male and the female have not mated recently they will keep
going for about 275 minutes, or 4.5 hours. However, if both have had sex
recently and thus feel a bit tired or drowsy or satisfied, then they
will limit they will stop after only 176 minutes or 3 hours.

Following not so much cuddling you depart, exhausted but happy. . .
However, for a ladybird sex is not just joy. Because ladybirds are
really really promiscuous animals they are also very often the victims
of sexually transmitted diseases, in fact the ladybird has more STDs
than any other insect. According to one estimate that I found, up to 90%
of some populations of ladybirds can be affected, so you better use the
condom (or become a ladybird nun).
