Are Geezers sleeping less than Whipper-Snappers?

According to an article titled Healthy Adults Can Get By With Less Sleep "older adults without sleep disorders can have a reduced “sleep need” and are less sleepy during the day than healthy young adults." Here are a few clips from the piece:

Researchers discovered that during a night of eight hours in bed, total sleep time decreased significantly and progressively with age.

Older adults slept about 20 minutes less than middle-aged adults, who slept 23 minutes less than young adults.


Doesn't it amaze you how many "studies" are going on these days? That said I don't know that I agree with the study. In my younger years I seem to remember staying up later and getting up way earlier than I do these days.. of course I am retired. What is your experience - are you sleeping less these days?
