"Sixty is the new 40."

It's a common aphorism we've heard for some time now, doubtless meant to calm us Baby Boomers who are growing so long in the tooth that we now need two hands to hold our toothbrushes. And reassuring it indeed is.

There's just one problem: it's a crock. Sixty is not the new 40. Here's 60 quick reasons why:

1. Somebody who is 60 remembers Betty White when she was middle-aged. To somebody who is 40, Betty White was always 90.

2. Somebody who is 40 does not remember Senor Wences.   

3. Somebody who is 40 was born in 1972. You don't even remember 1972, not only because you were smoking dope most of the time but also because you don't remember 2013.

4. Somebody who is 40 did not grow up longing to be the fourth Cartwright brother on Bonanza.

5. Somebody who is 40 would never use the phrase "he looks like Walter Brennan" to describe someone perceived to be old-looking. 

6. Somebody who is 60 thinks Coldplay refers to the last time he tried to put the moves on a woman. 

7. Somebody who is 60 thinks of John F. Kennedy as part of "the modern era." To somebody who is 40, John F. Kennedy is as much a part of "the modern era" as somebody who is 60. 

8. Somebody who is 40 does not long for Bonomo's Turkish Taffy. 

9. Somebody who is 60 remembers the 1950s. To somebody who is 40, the ‘50s’ refers only to the next decade of their lives, which they are dreading.

10. Somebody who is 40 is not truly feeling the pain that Davy Jones is gone. 

11. Somebody who is 40 has never sung along to the commercial “If you want shoes with lots of pep, get Keds Kids Keds!”

12. Do you really think somebody who is 40 would find the concept of identical cousins credible?  

13. You take comfort in the fact that you are not old because you never liked Lawrence Welk. Somebody who is 40 thinks you are old because you liked Led Zeppelin.

14. Unlike somebody who is 40, somebody who is 60 does not think Winky Dink is just another cutesy name for you know what!

15. Somebody who is 60 has black and white memories. 

16. Somebody who is 40 thinks of Peggy Lipton as an obscure old-time TV actress who is the mother of actress Rashida Jones, not as the hot unobtainable chick sandwiched in between the two no-talented lummoxes on The Mod Squad. 

17. Somebody who is 40 may well think Buffalo Bob is a talking buffalo.  

18. Somebody who is 40 does not think it is hilarious when you shout out "I want my Maypo!"

26. You find yourself beginning to use the expression "a young fella." At least one of the times you have used the expression "a young fella," you were referring to somebody who is 40.

28. Somebody who is 40 thinks Cher has always been a solo act.

60 IS THE NEW 60!

And you know what?  

Maybe that's even sweeter.
