Nowadays, the younger generation is smart enough to not blindly follow or offer respect to any individual only on the basis of one's age or outward appearance.
Let us encourage each other in sharing knowledge.
I have often heard of that we should respect elders & this should be the case but still I don't feel that this should always be the case as each one of those are not respected.
What each one of us do in our personal lives even in context of our habits is a different thing but becomes very important when that activity also having an impact on us. For example, habit is not based on the age but is just a matter of our past that once were aligned to. Few of them which are also most commonly seen are smoking cigarettes, being alcoholic, eating gluten etc. In addition we can include telling lies or theft or others similar activities which I don't even want to list here but should be understood.
So is absolutely perfect to differentiate while showing respect to others as all are not of that level.
