I am planning to retire but now here come opportunities - should I stop working or keep going?

Just because you can retire doesn't mean that you should. Some people get a lot of joy out of their work and may be happier to take on new challenges than living at a slower pace.

While the average 20-year-old has more energy than the average 61-year-old, it's possible to stay healthy as you age. You can still be active and exercise in your 60s.
