Every doctor may have their profitable years, where they have been established and examine lots of patients. But it would not be the same in the following years, perhaps in the age of 55 or 60, they may no longer be capable to do operations, which are the main revenue generator in the healthcare industry. In my opinion, there is uncertainty in the projected growth/loss of the clinics, where usually (in Indonesia) the patients look for a certain doctor, not the institution. How can one value such case?
