Let us love nobly, and live, and add again
Years and years unto years, till we attain
To write threescore: this is the second of our reign
Love was as subtly catched, as a disease;
But being got it is a treasure sweet,
Which to defend is harder than to get:
And ought not be profaned on either part,
For though 'tis got by chance,'tis kept by art

Autore: John Donne
