Tro eller vetande?
Lite då och då återkommer jag till vikten av att veta, inte tro. Det gäller det mesta och självklart så borde det gälla inom all vetenskap. Inom klimatforskningen tros det enbart vilket alla insatta fattat. Ett annat område är inom medicinen. Där har man sagt att man kan få lungcancer av passiv rökning, vilket jag aldrig riktigt trott på av olika skäl. Till min glädje händer det saker inom det forskningsområdet.
"Investigators from Stanford and other research centers looked at data from the Women’s Health Initiative Observational Study (WHI-OS). Among 93,676 women aged 50–79 years at enrollment, the study had complete smoking and covariate data (including passive smoking exposure in childhood, adult home, and work) for 76,304 participants. Of those, 901 developed lung cancer over 10.5 mean years of follow-up.
The incidence of lung cancer was 13 times higher in current smokers and four times higher in former smokers than in never-smokers, and the relationship for both current and former smokers depended on level of exposure. However, among women who had never smoked, exposure to passive smoking overall, and to most categories of passive smoking, did not statistically significantly increase lung cancer risk. The only category of exposure that showed a trend toward increased risk was living in the same house with a smoker for 30 years or more."

Vad man ville var att få bort rökningen från allmän miljö, men man fattade att det skulle bli svårt så man drog till med lungcancer. Fula trick alltså.
Jag röker för övrigt inte.
