I only voted in assumption. In reality, life doesn't have a price tag. We tend to need more as we grow. The projections of today might not be anything significant in few years to come. I think one just needs to keep working as long as you have the strength. Besides we don't just work for the fund, there are fun and physical benefits in being active daily.
There are heaps of benefits to work - something too many young people might never realize until it is too late.
