This is a very good idea. Most of the people do not bother learn up to date information once they had their doctorate degree. This is a very big problem in higher education. Lots of things are changing rapidly day by day. It is always good to keep up to date information. This is a very big problem in the most of the Universities. They do not want to learn once they get tenured or job guaranteed . They think they are the most accomplished people on the earth. I wish the PhD%u2019s should be valid for only five years. . It can be renewed based on their research, publications and performance.
