How to be less stressed?
I have seen many times that people who smoke regularly and are chain smokers are not having any problems as you have mentioned. They are roaming very freely and seem tension free.
I feel it is the stress that causes cataract and other problems and not alcohol or smoking. It does not mean that I support smoking.
So the question is how to get free of stress or feel less stress? I have found that people of around 80 years old with a weight of above 100 kgs doing well while they drink lot of alcohol or smoke daily and still do not have any heart problems or high blood pressure or eye disorders (other than spectacles).
