Could the disintegration of the state of Alexander the Great have been avoided?

Perhaps, if Alexander had lived a long time and was able to reform the state, making something solid out of it, reliably connected by economic ties. In this sense, the Achaemenid empire of Tsar Darius III, which he defeated, looked more viable. Alexander the Great died at the age of 32. It would be good if he lived as long. Some rulers of antiquity, for example, the Egyptian pharaohs, lived up to 60-70 years.
