Longevity vs Retirement Age

A friend e-mail an interesting article - the Longevity vs Retirement Age caught my attention.

This article "Optimum Strategies for Creativity and Longevity" by Sing Lin PhD said that

1. The most Creative year is 10 years around age of 32
2. If you can retire earlier you will live longer (as you are less stress as you are financially sound and has an enjoyable retirement)

It sound logical.But there are article to contradict this published by BBC News that titled "Early retirers don't live longer"

This article point out that

1. Health is an important factor, if you retire because of poor health you may not live longer.
2. Greater social engagement and involvement improve the health of older people.
3. After retirement it important to stay mentally and physically active.

Both has it points. One is study at America while the later is on British. Perhaps America and British is different. What about Asian or Malaysian? Anyway stay happy and enjoy life. I think that is most important after all you never know when your time come.
