why wont the doctor participate in the expiriment? what evidence suggests that he has anticipated the outcome of his test?
Before you drink, my respectable old friends," said he, "it would be well that, with the experience of a lifetime to direct you, you should draw up a few general rules for your guidance, in passing a second time through the perils of youth. Think what a sin and shame it would be, if, with your peculiar advantages, you should not become patterns of virtue and wisdom to all the young people of the age!
These words by Dr. Heidegger issue a warning to his friends and subjects that he knows they will not be able to resist. They want to prove that they can reverse their previous sins and poor choices if given a second chance. Everybody wants to believe this about himself!
Yet, Dr. Hiedegger announces he will not be participating because he does not have any desire to revisit his youth. He knows that the outcome will be chaotic, counterproductive and damaging.
The doctor knows that the results of his experiment are only temporary. While the friends do reclaim their youth and vitality, they show no signs of changing their previous ways. Then, as the effect wears off, Dr. Hiedegger admits that he would never partake in this experiment. Once the people have a taste of youth, it becomes like a drug to them, they continually seek it no matter the cost.
