I recall reading, a long, long time back, a poem called "The Blind Man and the Elephant" ... this poem was all about how six people of "Indostan" look at an elephant and try to express their impression of their observation (pardon the mouthful here), and how each arrives at a different conclusion about the same object. This poem has been subseqently seen under different avatars and stories, but thats not of importance here.
At that time, I remember my curiosity getting all perked up, and much to the worry and chagrin of my parents, and their parents (nothing above that, thankfully), I would try to explore various objects in and around home with my eyes closed. My grandmom maintains till this day, that this is the reason I am wearing specs. Not a point of view that learned savants and docs agree to, but you cant argue with grandmoms, whatever generation you are in.
