I believe the answer is: Wisdom
Wisdom influences our ability to use the knowledge that we have in order to make a good judgment.
As we got older, our brain's function will deteriorate. But, older people tend to accumulate more experience compared to the younger ones. Those experiences will provide older people with knowledge that might not be known by younger people. They could use it as a core strength to make better judgments than younger people.
They avoid being detected because this would throw off the behavior patterns that exist naturally and they don't want their presence being known since this might throw it off.<span />
