Here's an interesting article from USA Today noting that after years of decline, the labor force participation of workers over the age of 65 is now at 17%. It's not particularly surprising if you consider that the life expectancy in the US has risen to over 78.4 years.
People are living longer than ever and rather than spend retirement years in frivolous pursuits, many are returning to the workforce. These former retirees are eschewing days on the golf-course for something more meaningful. Often they are pursuing these "encore careers" in education or other non-profit sectors.
Since the Bible does little to support the idea of retirement at 65, most Christians aren't typically the retiring type. Instead, we reminded that God calls and appoints us to bear fruit, presumably as long as we are able.
"You did not choose me, but I chose you and appointed you that you should go and bear fruit and that your fruit should abide, so that whatever you ask the Father in my name, he may give it to you." John 15:16
Jesus may have been speaking to the disciples but his words are nonetheless applicable to us as well. Paul asserts as much in Ephesians 2:10 where he speaks us as having been "created in Christ Jesus for good works which God prepared beforehand that we should walk in them". Consider this remarkable thought - God has prepared good works for us. A few of these works take on grand significance but most will seem mundane. Yet each act, big or small carries eternal significance in the economy of God's plan.
Leisure and entertainment may have their place, but it is God ordained work that occupies the centerpiece of our daily existence. By God's grace, may we be both faithful and fruitful in the work He has appointed for us.
