I must advise all you youngsters of a salient fact.
There is sex after 70.

Thus ably debunking Tom Lehrer's take on the old "gather ye rosebuds while ye may" line:

An awful debility, / A lessened utility, / A loss of mobility / Is a strong possibility.
In all probability / I'll lose my virility / And you your fertility / And desirability.
And this liability / Of total sterility / Will lead to hostility / And a sense of futility.
So let's act with agility / While we still have facility, / For we'll soon reach senility / And lose the ability.
