Dr P is appears to be a very youngish 70 or so man. I don't believe making more money is the driving force behind his actions. He could probably just sit back and smell the roses. In leronlimab he has found a chance to leave his mark on the world. I believe that helping save the world and healing humanity is much more important to him than any financial gain. The recognition he could achieve at his age is a nice plus.
