A New Wrinkle (edit4)

[TranquillityBase]

edit2;


I wear the darkly shaded eyes of age:
a newly sagging epicanthic fold–
so few fast-burning decades since my birth–
surprised me.  Shall I yield to weary rage
embittered at this mark of growing old
or welcome rest’s approach a shadow’s-worth?

  "weary rage" hits the right note, as do the other edits.  I'm not sure about "fast-burning decades".  Just an uneasy feeling that it's too close to "burning candle at both ends" and similar references.  Maybe something more neutral to modify decades?
