(Brain Damage by Smoking)
Damage to the brain's outer layer caused by Smoking may be reversible after quitting, but it
Could take years, a research revealed.

Brain scans of 500 Scottish septuagenarians confirmed a link between smoking and an acceleration of age-related thinning of the cortex—the outer layer of grey matter, researchers reported. But they also pointed, for the first time, the potential for recovery

after quitting. The cortex of ex-smokes in the group "seems to have partially recovered for each year without smoking", the multinational research team wrote in the national journal molecular psychiatry. But, they warned that:" Although partially recovery seems possible, it can be along process." Many studies have linked cigarette smoking with cognitive decline and dementia, that smokers have, on average, slightly poorer global congitive functioning in later life, as well as lower mean scores on cognitive flexibility and memory".

All the atoms of a given element are identical in every respect, having the same mass, size and chemical properties. Atoms of different elements differ in mass, size and chemical properties. Chemical combination between two elements consists in the joining together of atoms of these elements to form molecules of compounds. Drawbacks of Dalton's Atomic Theory It is now known that some of the statements of Dalton's Atomic Theory of matter are not exactly corre...
