These electronics can sometime drive u mad . Yesterday i just could not get an excess to my mail , give response to anybody for quite a while and then i gave up. Today as i finished endoscopy in an aged and quite a weak person , i lost all the data from my computer and could not give the video of the procedure . I felt so much humilated by the experience , but as the video recording was absolutely must for the further treatment of that patient i requested the gentle man to again subject himself to undergo the procedure , gratefully he agreed and i was very very thankful for his cooperation with me .
