Many seniors I have met seem to have a switch in their heads that flips somewhere around the age of 70. Suddenly they become super frugal. Even as the estate continues to grow. Both curious and unsettling.

On another note, a comment in the article mentions that "most" financial advisors accept a 6% withdrawal rate as safe. I have never heard of this before. I know 4% is considered as rock solid and your value should continue to grow. I view 5% as very safe. 6%? May be pushing your luck a bit.
