Stephen Roissi (Philip's investor, 45-55) is an eccentric businessman who has pulled himself up from modest
roots into a life of wealth and success. He has attained a near-celebrity status as a proponent of "life-extension"
and believes that science, technology, and medicine will be able to make staggering advances towards combating disease
and aging and ultimately extend the human life-span indefinitely. The spark of possibility from Philip's remarkable
discovery combined with his confidence inspires Roissi to make an extremely risky investment with the young scientist. |
