Satchel Paige, who played professional baseball until the age of 59 was quoted as saying, "How old would you be if you didn't know how old you was?"
I love this quote.
I exercise at the YMCA most weekday mornings and in general, it's a more elderly crowd at 5:30 AM.
By around 7 AM many are gathered around a table drinking coffee and discussing just about any topic.
I get to join in for a short time, on most days.
I know many are in the 70's and 80's; even one in his 90's.
David, Tommy, Jerry, Alice, Kathy, Dan and Oscar; to name a few.
They would all make Satchel Paige proud.
"Research has shown that the most satisfied and successful older adults are the ones who don't focus on age, on their physical changes (within reason), or the stereotypes about age that are so prevalent in our society."
They're great role models for remaining younger at heart than their chronological age.
