Smoking Damages Your Health - Quickly

Some new medical findings can be a bit "oh-hum". It has been found that smoking, just intaking smoke from one cigarette, can damage DNA almost immediately. This does make one think about not taking up the habit. However, it is widely accepted that danger is only there after smoking for 20 or 30 years.

So much work has been done on tobacco. Very little on the other widely used smoking drug - marijuana. Stay away from cigarettes one may say and partake of weed instead. Apparently, the intake of grass is quite safe.

Why is there such a desire for humans to consume such a highly addictive naturally occurring compound? It all boils downs to evolution, natural selection. Unless something you consume reduces your competency to reproduce until the age of about 25, genes will not be selected to combat it. Whether smokers die later in life when they are way past producing and bringing up offspring is irrelevant to survival of the species.

Smoking is like drinking alcohol - it is enjoyable at the moment of consumption but later you may suffer consequences. Restricting sales may be the wrong thing to do. If people want to damage themselves why shouldn't they be allowed to do it? There are so many social problems out there. Concentrating on just one of them is really a waste of resources.

Danger From HIgh Salt Intake Is Overstated

Salt will kill you. That it is the idea we are all expected to accept, but there is no real proof that this is the case. No research has indicated that a high salt diet increases blood pressure. Indeed, a century ago Africans would travel a thousand miles to get it. Salt is essential for life.

Consumption 50 percent higher than the recommended level is nothing to worry about, considering it is only a "guesstimate" anyway. High blood pressure has increased in the community despite salt intake remaining about the same per person for 40 years.

Like a tax on fast food will not stop people from buying take away, so campaigns to reduce salt intake will not make people consume less. If manufacturers of processed food take salt out of their products consumers will not buy their products. Salt definitely improves flavor.
