excess drinking will not only lead to health problems, but to a lower mood (19) whenever you face any problems. and it can’t help solve the problem you may have.
smoking is another bad habit, just like drinking. although some people say cigarettes can, to some degree, reduce the stress (20) and make them manly, cigarettes can also destroy your appetite. smoking can make exercise and even normal activity such as walking across school or climbing stairs more difficult? not to mention causing heart and lung problems and increasing your risk of cancer. many smokers who give it up find they have more energy, so do not think that smoking is interesting.
