Sej pravim, da se dohtarji glede tega ne morejo zediniti. Link. Citat:

In total, around 17,000 people were included in the study. Significantly, more men than women
were left handers, but gender was not itself associated with increased risk of inflammatory bowel
disease (IBD). But later birth was, with those born in 1970 more likely to have IBD than those born
in 1958. Altogether, 71 people had either confirmed Crohn’s disease or ulcerative colitis, with left handers more than twice as likely to be affected overall. A similar pattern was found for Crohn’s disease
and ulcerative colitis when the two diseases were looked at separately. Left handedness has been linked with various autoimmune diseases, including asthma, migraine, autism and diabetes, but so far, no one has been able to pinpoint why. The authors point to previous research showing a seasonal variation in the birth of left handed girls, which, they say, might implicate some environmental factor.
Another, somewhat controversial, explanation is the amount of testosterone a fetus is exposed to
in the womb, which may affect brain and immune system development.

Ja, ampak to še ne pomeni, da je to glavni vzrok. Lahko bi recimo bilo tudi to, da so levičarji bolj 'pustolovski', več tvegajo in zato je večja možnost, da umrejo v nesreči. Ampak za take analize bi moral imet podatke o vzroku smrti - naravna, nesreča, bolezen...

ki jo je prav v ta namen nosil s seboj.

Thomas ::

Vseeno je, kakšen je povečan vzrok smrti levičarjev. Sem samo rekel da je - IMHO - to realen fenomen.

A study claiming to show that left-handed people die
nine years earlier than right-handed people relied
faulty statistical methods, according to scientists who
have reviewed the research. The study was published
the New England Journal of Medicine two weeks ago, and
received wide press coverage.
Stanley Coren of the University of British Columbia
and Diane Halpern of the California State University
San Bernardino relied on death records for their study.
They obtained records of 987 people who died in two
counties of southern California. Family members told
Coren and Halpern whether the deceased people were
right or left-handed.
Coren and Halpern then calculated the average age
which the right and left -handers died. Right-handers,
turned out, died at the ripe old average of 75. Those who
preferred their left hand died at an average of 66.
But Coren and Halpern never found out how many left
and right -handers there were in those two counties
California to start with, much less how old they were.
a result, their results “mean absolutely nothing”, says
Tricia Hartge, an epidemiologist at the National Institutes
of Health.
The American Academy of Actuaries also issued
statement calling Coren and Halpern’s methods “faulty”.
Richard Labombarde, an actuary with the private firm
Milliman and Robertson in Washington, says that Coren
and Halpern’s research reminded him of methods used by
actuaries 200 or 300 years ago.
Coren and Halpern’s result, says Hartge, may simply
reflect a well-known fact: the average left-handed person
in the US is significantly younger than the average righthanded
person. This may have nothing to do with the life
expectancy of left -handed people. It is probably due to the
practice, common until recent decades, of forcing lefthanded
people to write with their right hands in school.
Because the population of left-handers is younger, the
left -handed people who die will, on average, be, younger
than right -hander people who die, says Hartge.
Coren denies that historical practices of forcing left -
handers to change could have produced his data. He says
that it is very difficult to persuade people to switch hands,
and even then, the people may write with the right hand
and do most other things as they did before.
But both Hartge and the Academy of Actuaries
dismissed the significance of Caren’s historical studies,
saying that only a valid study of life expectancy could
resolve the question. This would require taking two
matched groups, one of left-handed people and the other
of right-handed people, and keeping track of how many
die as they get older. Apparently no such study has been
done

V bistvu tut tista druga varjanta od mamic ki so otroke učile pisat s "talepo rokco" ni čist izključena (vsaj pomoje). Fotr od moje boljše polovice je za vsakič ko je prijel svinčnik z levo roko dobil po roki in ga mogu dat v desno. Zakaj? Zato ker je njegova mama verski fanatik. Rezultat tega je da piše z desno roko. Njena mami tut. Glih zanč smo se pogovarjal o tem, in sta rekla da na vaseh zelo zelo redko kdo piše z levo (pač vpliv cerkve, starih mam,...).

Sicer pa kje sploh piše da sm jst desničar al pa levičar? od kje jim podatki za statistiko?

Thomas ::

Sej problem je v tem, ker statistika je tukaj švoh. Ja - sej kje pa ni? No, statistika kot matematika je na visokem nivoju. Kot empirija, kot podatki iz opazovanj je pa ponavdi švoh ali celo podn. Se strinjam s tabo, da so včasih zatirali levičarjenje. Ampak še bolj so zatirali samozadovoljevanje - ampak a misliš, da so ga kaj zatrli? Dvomim. Tko da dedek 80 let star, ti bo po moje le zaupal, da je levičen. Ne bo ti povedal, koliko sperme je lastnoročno pridelal. Da mu je levica bolj pripravna, pa najbrž le bo priznal.

Ampak nekako takih dedkov (tudi babic) v populaciji 80+ baje kar ni. To bi lahko pomenilo - IMHO - le eno. Da so red že povečini umrli. Logika je neizprosna.

To je sigurno precej dobro delovalo na psiho tvojega očeta. Sicer pa je to spet prikaz, česa se poslužujejo "ponižni verniki" RKC. Glavno, da gredo drugo nedeljo k spovedi, pa jim bo vse odpuščeno... otrok pa bo postal psiho. ;)

||_^_|| ::

IceMan: hehe, ne gre za mojga očeta. O vernikih se pa strinjam, ampak to ni prava tema:)

Thomas: Ne gre za dedke, gre za ljudi k so zdej stari 35-45let in pišejo z desno čeprav so po defaultu levičarji in vse ostalo delajo z levo. Statistika je pa tuki zelo švoh ja.

R0K ::

- Cigareti, Coca-Cola, fast-food (čeprov slednji dve ljubim je to samo sranje...)
- Mobilni telefoni (nimaš več mira pred nikomer)
- zakoni, ki z leti omejujejo določene možnosti opravljanja raznih izpitov (za avto 18., za srednjo šolo moreš dokončati OŠ, itd. Bolje bi bilo, da bi se opravil preizkus če si dovolj dober za to, leta nebi bila pomembna. Marsikdo je pri 15 lahko tako resen, pameten, iznajdljiv, whatever kot en pri 25.)
- Širjenje civilizacije. Če bi nas bila samo miljarda bi bilo ravno dovolj. Preveč folka, narava se preveč uničuje, luft je vedno bolj v kurcu, vsi strmi preveč k denarju.

(ps: se opr. ker zadnja dva nista 'izuma' sam mislim, da spadata v to temo)

Nevednez... :P

To so poceli se kar nekaj let po 2.sv vojni v solah. Tam je bilo precej malo cerkve... ;>

Big: zakaj pa to?

BigWhale ::

Nevem zakaj, bi moral koga prasat. ;) Moj fotr je precejkrat rekel, da je sel tepen iz sole, ker je hotel z levo roko pisat...

Hm, poleg 'Ko bi tega le ne izumili...' bi bilo zanimivo videt se kaj v stilu, 'A tolk casa so nucal, da so tole pogruntal?!?'

My all time favourite je jasno samolepilni trak na otroskih plenicah (Pampers), ki so ga mogoce kaki dve leti nazaj reklamirali prav na veliko... Prava revolucija v proizvodnji otroskih plenic... ;>

Podaj primer kako se da z mikrovalovko pretiravat.

Do nedavnega so pa pretiravali s štedilniki in pečicami na plin ter elektriko, in? Se bojite napredka, neka fobija, ali kaj drugega? :)

Phoebus ::

Mal sem pozen z lucko ampak vseeno- USB lucka zna biti ZELO uporabna za uporabnike prenosnih racunalnikov tam kjer ni vticnice in imajo kaj resnega za delat v mraku - osvetli tipkovnico, okolico laptopa, prenosni printer, ali karkoli pac rabis osvetlit.

Za uporabnike desktopov je pa seveda neuporabna in se zdi blesava.

Mchaber, bullsh!t. Veliko več nevarnega sevanja producirajo televizorji in monitorji s katodno cevjo. Pa se nihče ne pritožuje čez njih.

Najbrz res ampak frekvenca s katero seva monitor je bistveno manjsa od frekvence s katero seva mikrovalovna pecica. V bistvu, mikrovalvna pecica dela tako, da se trudi zanihat molekule vode v stvari, ki jo pac grejes...

... v nasem telesu je pa tako ali tako samo 70% vode... ;) Ni strahu! :P

Da niti ne omenjamo sevanja GSM aparatov.... :)
