i dont know what you guys do in economics or some other subjects as i have done my ph.d. in biotechnology and have put 5 years of hard work regularly for doing it............ we sometime need to work 48 hrs continuously......... i have learned many more thing then just getting a degree.......... we cant do our ph.d. part time....... i have international publications also........ i have done my ph.d in india only....... after all these years of hardwork, frustration (when experiments fail), patience what i am hearing is that this should have expiry date....... see if i ll work then it ll be valued and if i dont work then still have spent my best years of youth in doing phd...... so it should not expire........ if i take a ten years gap after that and dont work then nobody ll give me job on the basis of my my phd but i ll still be a doctor of philosophy no matter what i do.............
