Sonnet 22 

1	My glass shall not persuade me I am old
2	So long as youth and thou are of one date#
3	But when in thee time’s furrows I behold,
4	Then look I death my days should expiate.
5	For all that beauty that doth cover thee
6	Is but the seemly raiment of my heart,
7	Which in thy breast doth live, as thine in me#
8	How can I then be elder than thou art?
9	O therefore, love, be of thyself so wary
10	As I, not for myself, but for thee will,
11	Bearing thy heart, which I will keep so chary
12	As tender nurse her babe from faring ill.
13	Presume not on thy heart when mine is slain:
14	Thou gav’st me thine not to give back again.
