Dr. Heidegger is an enigmatic old medical doctor who performs an experiment on his four elderly friends to test the hypothesis that youth is inseparable from folly. Though Dr. Heidegger is a scientist, his study is filled with magical objects and his experiment involves magical water from the Fountain of Youth.

What was Dr. Heidegger's real experiment?

While he spoke, Doctor Heidegger had been filling the four champagne glasses with the water of the Fountain of Youth. It was apparently impregnated with an effervescent gas; for little bubbles were continually ascending from the depths of the glasses, and bursting in silvery spray at the surface.

What is Dr. Heidegger's personality?

Heidegger is a man with a profound interest in both science and the occult, or supernatural. He speaks to a bust of Hippocrates, the father of medicine, about his medical cases, but he also keeps a heavy book of spells.
