Let's clear up a few things.
Most smokers do not die in their 50s or 60s.
Most smokers die not that much earlier than people who don't smoke BUT and it's a HUGE 'but'- they have appalling quality of life for many years.
It's not length of life that counts but quality.
Smokers get any of the cancers that non-smokers do, but their risks are higher. So that's bowel, throat and mouth, breast, lung and for women, cervical cancer.
Add to that a whole range of bronchial disease, and heart /circulatory diseases.
This attitude 'oh but we all die anyway and won't get dementia' is a cop out! you are FAR more likely to get dementia in your 50s or 60s as a smoker than a non smoker is. Smoking hardens the arteries to the brain and destroys blood flow to the brain - this is what vascular dementia is- and the die off.
So the idea you can smoke for decades then pop off with an easy death is laughable.
@womaninchains. You have a right to smoke. Everyone else has the right to clean air. This is the bit you aren't accepting. The fact people are commenting, is a sign they are not happy about your smoke.
How odd you come here to defend yourself rather than asking for help to give it up.
Why is that not an option for you?
