The second edition of Outlook Money’s 40After40 Retirement Expo got off to a fabulous start with the theme address of V. Vaidyanathan, MD & CEO of IDFC First Bank. Speaking on the occasion, Vaidyanathan exclaimed that senior citizens are "young" and what was 60s earlier is now 80s. “With the life expectancy and level of fitness rising, 80 is the new 60”, he said adding that it is all about how you approach your life. “It is you versus what you were 20 years ago, approach life with curiosity.”
