Whether '\''tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles,
And by opposing end them? To die: to sleep;
No more; and by a sleep to say we end
The heart-ache and the thousand natural shocks
That flesh is heir to, '\''tis a consummation
Devoutly to be wish'\''d.

When we have shuffled off this mortal coil,
