Is it wise for the afterlife?
Possibly, BS baffles brains etc. Some roles in civ div demand it in the same way they demand Prince 2 - no one uses Prince 2.
It depends on the sort of decisions you are making. I know when making safety-related calls and anything else to change equipment use etc, professional accreditation is preferred and makes things easier.
Doctors and lawyers need that sort of membership - is it not just a sign of increasing professionalism and having something everyone understands?
