Time passes

"Eheu fugaces, Postume, Postume, labuntur anni."

"Alas, O Postumus, Postumus, the years glide swiftly by." 

Horace

"There is no funeral so sad to follow as the funeral of our own youth which we have been pampering with fond desires, ambitious hopes, and all the bright berries that hang in poisonous clusters over the path of life." 

Walter Savage Landor.

"There are not many Doctor Johnsons, to set forth upon their first romantic voyage at sixty-four." 

Robert Louis Stevenson, Virginibus Puerisque

O that I were an orange-tree. 

That busy plant! 

Then should I ever laden be. 

And never want 

Some fruit for Him that dresseth me. 

But we are still too young or old; 

The man is gone. 

Before we do our wares unfold: 

So we freeze on. 

Until the grave increase our cold. 

George Herbert, after whom so I once read George Herbert Walker Bush was named - but it seems the poet was not an ancestor of his and his baleful son.
