Threescore Years and Ten

Months run into years and years into old age and the visions of youth fade into advancing life.
Finally, to be 70 is to have lived 30 percent of the life of this nation, which is almost enough time to begin to fully appreciate the inestimable privilege of being a legatee of those who first unfurled the republic’s sails and steered it toward the present. That is why — with homage to F. Scott Fitzgerald — as we beat on, boats against the current, we should be borne back ceaselessly into the American past: It is impossible for the young to know, but never too late to learn, that America truly is something — perhaps the only thing — commensurate with our capacity for wonder.
"The Wonders of Being 70" by George F. Will
I am able to say that while I am not ruggedly well, I am not ill enough to excite an undertaker. ... I’ll forget the Lord’s middle name some time, right in the midst of a storm, when I need all the help I can get. --Mark Twain
"Being seventy is not a sin." --Golda Meir

"The years between fifty and seventy are the hardest. You are always being asked to do things, and yet you are not decrepit enough to turn them down." --T.S. Eliot

"We know the past but cannot control it. We control the future but cannot know it." - Claude Shannon

"As ye pass by the tomb where my ashes consume, Oh! moisten their dust with a Tear." ("The Tear" by Lord Byron)

"And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years." Genesis 6:3 (KJV)
