Hey Dada Giri, You are 'Kathakar the great'. I really enjoyed reading this thread and spend my whole day. I was supposed to look at some journals in the pubmed for my project but i could not help myself to stop reading your thread. BTW, why did u put giri in your nick name? is Sanju is from giri family and it so happened that you changed your surname from paudel to giri (jut my guess only). Expecting to get your version of explanation.. Keep it up. Nut
