People race to achieve everything by a certain age in their life, be it 40, 50 or 60 - but with increasing life spans 50 or 60 might be just the beginning of a new career, or just the point when you begin to get into your stride. There used to be a syndrome of me retiring at 65 and then dying not long after because their life was stripped of meaning, without their work. But these days you may live another 20 or 30 years beyond 65 so you have to figure out where you can make another contribution.
