I'm guessing he isn't doing it himself because he's 61 years old. His odds of dying are maybe 10-100x higher than the perfectly healthy twentysomethings that he's proposing for an initial trial.
Well, he is the one that is arguing that there is some linearity between cost-benefit of such a research. So following his own reasoning, as long as he gets 10x-100x bigger payment compared to a twentysomething, all is good and clean.
There are moral considerations to be done before proposing something ridiculous like what he is doing, and yet he is trying to reduce all ethical considerations into a "simple" matter of economics. Life can not be reduced to spherical cows and trolley problems.
