2. Smoking
As unbelievable as it may seem, we have known about the dangers of smoking for decades and still, there are young people taking up smoking every day. The age-old perception that smoking is “cool” is still alive and well despite all of the warnings issued by government officials and education programs that attempt to make young people realize that smoking is a very real threat to their lives. Sadly, many of them will only realize the consequences of their decision to take up smoking when they find themselves being treated for cancer in their later years.
