Maxim Leo has written several bestsellers. He received the European Book Prize in 2011 for his autobiographical work "Hold Your Heart Ready" In his new novel “We Will Be Young,” Leo addresses a question that is one of the oldest in human history: What if we could stay young forever? He describes the moral dilemma a society finds itself in when a lifespan of 120, 150 or even more years is the norm.
