Sitara, Happy new year (the Chinese one?:) It seems that I do need to change my glass! "My friends and I have not yet hit graying time yet - it is still entirely black and mostly intact :) " Captain Saap, No! To some people like me, "Graying" DOES NOT relate to "time" or "Age". It comes unnoticed and when we DO notice it, it is already too late to worrry about. When I do not see mirrors (perhaps due to psychological reasons, I seldom look at mirrors-- let me grow my beard than to feel too old) and the fallen hair in the barbar shops, I still feel like 20 :) My experience is that WAY of THINKING does not change a lot (it must be genetic factor) but the knowledge does (with age and with education). No matter how old I am, I am still thinking iin the same way as I was in undeegraduate student.
