My dear youngsters,
Urmila has rightly said that we must see the merit/content in someone's posts. Age is just a digit and there is no prescribed benchmark for a man to be called old. However, a man may be termed as old when he becomes incapacitated in certain important matters which I need not to elaborate. Some of them really rock even at the age of 75.
We tend to forget that without the contribution of these so-called '"Budhas" (elderly people) our existence in the world would not have been possible. In that sense they are our creators. Therefore, one should not disregard these great "creators" just because of their age. Please note that when the "creators" will really get old, they themselves will stop putting their beak in your soup. Till that time please let them have some good time.
PS: My above comments are not meant for Urmila. I have simply quoted her post for those who have scant regard for "Budha"
