Many has associated grey hair to represent wisdom or experience. Grey hair represent the old who have gone through so many things in life, have experience a lot have enjoyed the good and endured the bad life has to offer. We respect this old people because they are seen as those who understands life better.
The question there is that does grey hair really signifies wisdom?
Does all the old folks possess Wisdom?. It is not true that they all have wisdom, but it is also true they possess wisdom, the one who wastes his life must have regretted from his mistakes it is also wisdom, the one who understands that in life you must keep pushing and never give up also is another wisdom.
Both poor and rich old folks still have some Wisdom to offer, it just depends on the side you want to take. A poor old man will tell how what he did that made him poor till now and also the rich old man can also tell you what made him rich till this age.
There is always a lesson to learn from the old
Grey hair is Wisdom.
